Viewers of The Great British Sewing Bee were stunned when the contestant revealed her age

Viewers of The Great British Sewing Bee were stunned last night after a contestant revealed her age from the show.

The seventh episode of the hit BBC series, which is hosted by comedian Sara Pascoe, aired last night as the amateur seamstresses got 90s week.

However, Mia, a student from Surrey, surprised many onlookers when she admitted that she was not born in the 90s – because she is only 20 years old.

She said, “I wasn’t living in the ’90s. I’m glad there was a resurgence recently or I’d definitely be in trouble.”

Viewers were surprised, with one comment: “I can’t commute this.” Even though my own adult(ish) son was born in 2001, I can’t fathom how adults weren’t born in the 90s.’

One wrote: ‘I have turned to dust. Somebody be a treasure and suck me up.”

Others confessed that they enjoyed the 90s theme show, commenting, “Love the 90s Sewing Bee soundtrack.”

Another added, “Sewing Bee is a 90s week and I feel old now. Tunes do!’

A fourth wrote, “Lovely 90s week at sewing bee tonight. Deffos my favorite decade. I was more grunge than Spice Girls.’

Another commented, “Love the ’90s on Sewing Bee, just singing constantly.”

First up, in the Pattern Challenge, the seamstresses are asked to make the most popular pants of the 90s: cargo pants.

Loved by hip-hop musicians and British girl bands alike, these pants feature unfamiliar bellows pockets and a fly zip.

The judges told her that her zipper was “too close to the edge” when she “didn’t have a buttonhole” and “hadn’t done the hem.”

They said the pants were already “unwearable.”

For the Transformation Challenge, the seamstresses pack home textiles and zip together a 90s celebrity fancy dress costume.

Mia said, “I found a lot of pink, so I think of Madonna’s cone bra.”

The judges said it “worked really well,” adding: “It’s a simple build, but it won’t fall open.” Very good, I like that very much.’

Finally, in the Made-to-Measure Challenge, the seamstresses take on the legendary supermodel dress.

Speaking of the tight black dress she designed for the final challenge, the judges said they wished she’d tweaked the hemline and added more necklaces

These bodycon and bodyskimming dresses encapsulate the glamor and decadence of the decade.

Despite Mia’s concerns about her age preventing her from excelling during the week, the 20-year-old surprised the judges with her creations.

Speaking of the skintight black dress she designed for the final challenge, they said they wish she’d tweaked the hemline and added more necklaces.

However, they said it “looked great,” adding, “It has the vibe we were looking for.” It’s very, very good.’

In the end, Mia managed to secure a spot in the quarterfinals, but it was Lizzie who discovered she was suspended from the game.
