The former Made In Chelsea star headed out on Saturday (15 February) to watch the Julien Macdonald show and bagged a seat on the FROW with her model pal Zara Martin.
But in a dazzling dress like hers, Millie might as well have joined the rest of the ladies on the catwalk!
Proving her enviable fashion credentials, the 24-year-old wore a gorgeous piece handpicked from Julien's new collection, which was made out of sheer material that resembled netting and covered with a strategically placed black sequin design.
Ooh la la!
Millie completed her look with a pair of plain black heels and kept her hair and make-up simple, so that her frock was the main focus.
Well, we certainly can't take our eyes off it!
It sounds like the two girls had a blast sitting on the front row at the glamorous show and while there, they also rubbed shoulders with fellow stars Abbey Clancy and Eliza Dolittle.
Millie exclaimed afterwards: "Such an incredible show! #julienmacdonald."
It's been a busy few days for the ex-reality TV star, as she and her husband Professor Green enjoyed a romantic trip to Paris to celebrate Valentine's day last week.
Returning to where they got engaged, Professor Green and Millie had plenty of fun in the French capital and even visited the restaurant where the rapper popped the question last March.
Although we bet the couple were reluctant to leave the City Of Love, we're sure coming home to London Fashion Week helped with the holiday blues!
