Former Made In Chelsea star Millie was pictured outside the Giles Deacon A/W '15 catwalk show and her faux pas didn't go unnoticed.
Earlier, Millie had been wearing a giant fluffy coat however, once removed, the camera bulbs combined with her sheer top and lack of bra meant we all got a glimpse of her boobs. Oops!
Either unaware or not bothered, Millie didn't seem to mind and was all smiles as she headed inside The College, in London's Southampton Row.
Supporting the designer, Millie's peach coat was a Giles Deacon number and she was quick to gush about it with fans. Taking to Twitter earlier in the day, she said: "It's been a fun few days! Excited for @gilesgilesgiles tonight #lfw."
London Fashion Week has been running in the capital since last Thursday and Millie has been a regular fixture at many of the runway shows.
On Saturday, Millie was pictured in the 'frow' of the Julian McDonald show alongside Rochelle Humes, Whitney Port, Ella Eyre and Michelle Keegan.
