The reality star - who is currently filming scenes for The Only Way Is Essex - looked seriously sharp and polished in this khaki two-piece which boasted high-waisted cropped trousers and a waterfall jacket.
Hands up if you think she should sport the sophisticated look more often?
Megan made her debut at the bash alongside TOWIE beau Pete Wicks (#CoupleGoals, right?!) and lengthened her already catwalk-worthy pins with a pair of peep-toe platforms, but it was her trademark big bouncy blow-dry that really drew gasps.
Of the good kind, duh!
Megs looked to Stawberry Glow salon in Woodford for her fabulously glossy tousles and sharp-as-hell contour which set her apart from all of the other guests, no matter how glam!
The stunner joined oh-so-stylish co-stars Danielle Armstrong and Georgia Kousoulou, not forgetting a virtually naked Marnie Simpson!
