Former Made In Chelsea star Millie smouldered infront of the cameras in this little monochrome number that featured sheer lace sleeves, fluted cuffs and a Peter Pan Collar that drew attention to the plunging cut-out detail across her chest.
Mills, who just released her very first book entitled Made by Millie, ramped up the sex factor and flaunted her yoga-honed legs in the 60s inspired thigh-skimming frock, teaming it with a sky-high pair of peep-toe platforms - perfect!
The dress is part of Millie's exciting new A/W collection available to buy later this month.
But Millie wasn't the only one to wow in an outfit that she designed, as MIC pal Binky Felstead rocked up in a military-esque shirt dress from her debut fashion line, too!
Even though Binks is keeping hush hush about her collaboration with a style hub that we all know and love, she told Reveal that the new drop is set to be a sell-out.
"I can't say who [the collection] is with yet but it comes out next week!" she said. "I believe that it will be a real success because any girl can wear it. It's pretty, quite elegant, quite boho-chic-ey."
Millie, Binky - we're spoilt for choice!
The stunner who normally wears her hair in cascading waves, geared up for London Fashion Week and slicked her honey-hued locks into a seriously fierce high-ponytail for the event in association with Visa, which brought TOWIE's Gemma Collins, singer Conor Maynard and actress Michelle Keegan all under one roof.
