Martha Stewart Shades Felicity Huffman's Prison Attire: 'She Looked Pretty Schlumpy'

Martha Stewart had a few words to share about Felicity Huffman‘s prison attire.

The home decor mogul, 78, spoke about the former Desperate Housewives actress, 56, at Vanity Fair’s 6th Annual New Establishment Summit on Tuesday in Beverly Hills.

Stewart was asked by CNN’s Brian Stelter if she thought Huffman had learned anything in prison, to which Stewart suggested, “She should style her outfit a little bit more.”

“She looked pretty schlumpy,” Stewart added, referring to photos of Huffman in her prison attire.

She continued, “She made a horrible mistake, and she’s experiencing what happens.”

Stewart served five months in prison and five months of home confinement in 2004 for lying about the sale of a stock that she owned.

In 2017, Stewart told Katie Couric on an episode of her self-titled podcast that the prison experience was “horrifying.”

“It was horrifying, and no one, no one should have to go through that kind of indignity really except for murderers, and there are a few other categories, but no one should have to go through that,” Stewart said at the time. “It’s a very, very awful thing.”

Huffman reported to prison last Tuesday to serve a 14-day sentence for her involvement in the college admissions scandal. She is expected to finish her sentence on Oct. 27.

In May, Huffman pleaded guilty to paying disgraced admissions consultant Rick Singer $15,000 to have a proctor change daughter Sophia’s SAT answers after she took the test.

On Sept. 13, the Emmy-winning actress was sentenced to 14 days in federal prison, plus a $30,000 fine, 250 hours of community service and a year of supervised release.

A source in Huffman’s circle recently told PEOPLE she is ready to pay her societal debts. “She’s embarrassed and just ready to get this behind her,” the source said, adding, “She wants to serve her time and move forward.”
