Jeans have been around since the mid-1800s and they've undergone a lot of changes.
In the 1990s, big and baggy jeans were a popular trend.
In the 2000s, skinny jeans and colorful jeans began gaining popularity.
Fashion trends come and go, but denim jeans are one item of clothing that will always be a staple in many closets.
It's the particular style of denim that changes year after year, some decades seeing a rise in baggy jeans, others full of tight, low-rise moments.
Here is a glimpse at what jeans looked like the year you were born:
The mid-1800s - 1930: Jeans make their debut and are known for being durable and practical, not stylish.
Back in the mid-1800s, when jeans were first invented, they were mainly popular with miners and workers who needed to wear something sturdy and reliable.
It took a few more decades before jeans became a casual staple worn by all genders on a regular basis
1930 - 1953: Jeans were Western-inspired and just getting popular.
It wasn't until the 1930s that jeans became more mainstream when they entered the Hollywood scene in popular Westerns.
Back then, jeans were associated with cowboys and the movie stars who played them.
Later, in the very early 1950s, jeans were just starting to become more of a fashion trend thanks to actors like Marlon Brando and James Dean wearing them on a pretty regular basis.
Still, even as they became more "cool," they had a Western vibe to them and were primarily worn by men.
It wasn't until 1952 when Marilyn Monroe wore a pair in her film "River of No Return" that they became a staple for women as well.
1954 - 1956: Boxy jeans were in style, and they were usually cuffed.
Throughout most of the 1950s, jeans had a boxy look to them — they weren't fitted or particularly baggy, they just looked rather stiff.
They were also almost always worn rolled up.
1957 - 1959: Pairing jeans with a white T-shirt became a trend.
This simple trend seemingly started back in 1957 when Brigitte Bardot was photographed in cropped, less boxy jeans with a white T-shirt.
Today, jeans and a white T-shirt are still a classic look.
Early 1960s: Denim became more flared, more embellished, and more fitted.
In the early 1960s, jeans were still boxy and cuffed, but as the years went on, they became more casual, more fitted, and more embellished.
They became more mainstream and less Western-inspired, too.
1964 - 1965: Jeans were tight at the waist and flared at the bottom.
The mid-1960s were all about flared jeans. Celebrities like Sonny and Cher, Twiggy, Mick Jagger, and Jimi Hendrix made the style even more popular.
1966 -1968: Boot-cut jeans took over.
Flares might have been a defining denim moment in the 1960s, but they weren't the only trend that people loved.
Boot-cut jeans were also very popular during this time, especially after Brigitte Bardot was photographed wearing them in 1966.
1969: Flared jeans came back.
Boot-cut may have taken over for a few years, but by 1969, flared jeans were back in business. Jeans were also becoming a little more low-rise.
1970: Jeans were more ragged and embellished.
An article in the New York Times about denim trends in the early 1970s said that patched jeans, frayed cuffs, and lightweight jeans were becoming more and more popular.
1971: They were more fitted in the waist.
Although flares and boot-cuts were still on-trend, jeans had become much more fitted at the waist. They weren't quite so boxy anymore.
1972: Bell bottoms made their way into the spotlight.
Flares seemed tame compared to the bell bottoms that became super popular in 1972. Jeans were more fitted at the waistband and got wider as they went down the leg.
1973 - 1974: Unfinished hems were on the most popular jeans.
Flared jeans and bell bottoms were still very trendy in 1973 and usually came with frayed hems that made it seem like someone had cut off a sliver of fabric.
1975 - 1976: Elephant bells became the new bell bottoms.
Bell bottoms got even more dramatic in 1975 with the introduction of elephant bells, which were basically just extremely wide-leg jeans that got even more flared around the calves.
1977: Slim, straight leg jeans had a punk-inspired vibe to them.
In the late 1970s, jeans started to become more slim-fitting, with straighter legs rather than flares.
For example, Levi's 505 jeans were particularly popular, especially in the music scene. You can tell by getting a glimpse of the Ramone's 1976 self-titled album, where they are all wearing 505s.
1978: Jeans became darker and tighter.
The punk-inspired look from 1977 stuck around as jeans became darker. They also became tighter.
Sasson jeans, which were known for being very tight, were incredibly popular in the late 1970s.
1979: Daisy Dukes took the place of jeans.
In 1979, actress Catherine Bach wore very short denim cut-offs in "The Dukes of Hazzard" TV series, and they immediately became trendy.
1980: Jeans became much baggier.
In the 1980s, the rise of hip-hop changed the way denim was worn. Jeans became very baggy and oversized.
1981: Jeans became more sexy.
It was 1981 when Calvin Klein released its ad featuring Brooke Shields that is still talked about today.
The then-14-year-old model infamously said, "You know what comes between me and my Calvins? Nothing." It wasn't the first time jeans had sex appeal, but it was definitely a big moment.
1982: Jordache jeans were the biggest trend.
Jordache jeans, with their stiff-looking fabric and embroidered back pockets, were one of the most popular brands at this time.
1983: Denim was high-waisted and cuffed.
In the early 1980s, jeans were high waisted, cuffed, and slightly baggy. This was when "mom jeans" really became a thing.
1984: High-waisted jeans had a slightly tapered leg.
Baggy, cuffed mom jeans soon became cropped, slightly tapered mom jeans, a trend that stuck around for a very long time.
1985: Jeans were tighter and cropped.
As the months went by, denim became a bit tighter instead of baggy or boxy. However, that slightly cropped ankle-length look stuck around — the better to show off your thick white socks with.
1986: Faded, acid-wash jeans took over.
Acid-wash denim will always be one of the first things people think of when they think about the 1980s, and for good reason.
Faded, super light acid-wash jeans were a huge trend.
1987: The acid-wash jeans got a little more destroyed.
Eventually, faded acid-wash also became destroyed acid-wash, with light jeans full of holes and artfully arranged rips.
1988: Denim-on-denim was a big thing.
As acid-wash jeans became slightly less popular, denim-on-denim got more trendy.
People were regularly photographed in slightly baggy, straight leg jeans with matching oversized jean jackets.
1989: Stonewashed jeans still held on as one of the biggest trends.
Similar to acid-wash jeans, stonewashed jeans were extremely popular. The worn-in, old look of brand new jeans was something everyone was wearing.
1990: Button-fly jeans were more popular than zipper-fly jeans.
Button-fly jeans were first introduced in 1954, and they came back courtesy of Levi's in 1990, when they became a trend once again.
These jeans utilize multiple buttons instead of a zipper closure.
1991: Overalls took the place of regular jeans.
Overalls were around before the 1990s, but this decade is when they really gained steam — especially in the pop-culture world.
Characters on TV shows like "The Fresh Prince of Bel-Air" regularly sported overalls, too.
1992 - 1993: Simple, straight-leg jeans were all the rage.
The jeans of the early 1990s weren't too outlandish. The most popular style was straight-leg, slightly stuff jeans in a medium wash.
Denim also saw a slight decline in sales around this time.
1994: Low-rise jeans took hold.
In 1994, low-rise jeans came back into style thanks to Alexander McQueen and then Madonna, who wore the butt-grazing jeans in a popular ad.
1995 - 1996: Boot-cut jeans came back.
In the mid-1990s, the bootcut style came back with a vengeance. They were straight, less baggy, and worn with just about everything.
1997: It was all about JNCO jeans.
Then suddenly JNCO jeans were everywhere. This huge, extremely baggy jeans were incredibly popular, accounting for an impressive amount of denim sales.
1998: And then it was all about Tommy Hilfiger jeans.
Once JNCO jeans started to lose steam, Tommy Hilfiger stepped in. The jeans, which were usually darker and always included the American flag logo, were seen on everyone.
1999: Medium-wash, classic jeans became big.
In 1999, Britney Spears helped popularize simple medium-wash jeans that had a tiny bit of flair at the end of the leg.
2000: Blinged-out jeans were a trend.
The early 2000s were a very weird time for jeans, where the trends got more and more intense with each passing year. It started with embellished jeans, which included lots of bling.
2001: Lace-up jeans were the new thing.
Blinged-out embellishments changed to lace-up embellishments as the months went on.
One brand in particular, Mudd, made some popular options: jeans that laced up at the fly, down the sides of the legs, or even up the front.
2002: The belt loops got very large.
The early 2000s is known for one strange accessory — extremely wide belts. As a result, many pairs of jeans had very large belt loops to accommodate the trend.
2003: Super low-rise flares came back in style.
The early 2000s were somewhat reminiscent of the 1970s thanks to the low-rise flared jeans that made a comeback. They were almost bell bottoms, but not quite.
2004: Back pockets disappeared.
For a brief period of time in the early 2000s, jeans lost their back pockets. In their place was often a semi-circle that called more attention to your butt.
2005: Capri pants made a comeback.
Back in the 1960s, cropped pants known as capris were in style. In the early 2000s, they came back in denim form, in all different kinds of washes.
2006: Ombré jeans became popular.
One popular look was for jeans to have a lighter wash in the middle of the leg, then darker at the bottom, supposedly to make your legs look longer. It gave almost an ombré effect.
2007: Jeans were low enough to allow your thong to peek out.
By this point in the early 2000s, low-rise jeans were so popular that many forgot what high-waisted even meant.
2008: Denim was anything but blue.
Instead of your typical medium-wash (or even light or dark), denim became colored. From gray to snake-skin to random patterns, jeans were anything but boring.
2009: Jeggings took over.
It was only a matter of time before jeans decreased in popularity after having an epic few years, and around 2009, jeggings took their place.
They were still technically jeans, but they were so stretchy that they could almost feel like leggings.
2010: Boyfriend jeans made their move.
Remember the boxy jeans from the 1960s that were once in style? They sort of came back in the form of boyfriend jeans, which were loose-fitting, cuffed, and sometimes destroyed in some way.
2011: Dark-wash skinny jeans became the norm.
It was either loose boyfriend jeans or tight skinny jeans, preferably in a dark wash. This was especially true after Kate Middleton was spotted in a pair during her 2011 royal North American tour.
2012: Jeans became bright and colorful.
It wasn't trendy enough to just wear skinny jeans — you had to wear colorful skinny jeans. This year, almost any shade was good to go.
2013: Patchwork denim was popular.
In 2013, jeans got a little bit more creative. Cut-and-wash combos were popular, as were patchwork and embellishments.
2014: Overalls made a comeback.
For a short period of time, overalls became trendy yet again. Although they were often worn loose in the 1990s, this decade preferred them more fitted and cropped.
2015: Jeans were still skinny, but also high-waisted.
As we moved further away from the low-rise jeans of the early 2000s, high-waisted jeans started to become more popular. In particular, 2015 welcomed high-waisted skinny jeans.
2016: Denim was cropped and flared.
The style from the 1970s was making a comeback, which was obvious in a big denim trend: jeans that were both cropped and flared out.
2017: Frayed hems were everywhere.
In 2017, the frayed hems trend that was popular in the 1970s came back into style.
2018: It was all about exciting new ideas and going viral.
2019: Denim jumpsuits and dresses were pretty popular.
Throughout the year, a number of celebrities rocked one-piece denim garments, from jumpsuits to dresses.
This popular look came in plenty of styles, whether you wanted a utilitarian suit that was cinched at the waist or a trendy number that was flared at the hem.
2020: Jeans weren't a huge trend, but baggy ones with a looser fit were favored.
Amid the ongoing global pandemic when many workers began signing on from home, cozy fashions took over.
Because of the shift, more structured fashions, like jeans, weren't a major wardrobe staple for some. But when people did opt to wear jeans, they tend to choose less form-fitting styles that were loose or had plenty of stretch.
