The Ex On The Beach star was snapped wearing the dusky pink number before heading out the door...but does it flash too much flesh?
Lillie's sexy frock features both a plunging neckline and a super-high split in the skirt, and it is seriously clingy to boot.
She seems to love it though, tweeting: "Another amazing dress from @dressmezara."
Judging by the comments from her fans, if anyone can pull this off, it's Lillie. One gushed: "Unreal!" Another follower even offered his hand in marriage. Err...ok!
Lillie is currently on our screens in MTV's EOTB and, in Tuesday night's instalment, Bear and Hawley go head-to-head as they try to win her over.
EOTB continues, 10pm, MTV, Tuesdays
