Beauty is pain!
The reality star posted a Snap of her legs after the event, and they looked like an annoyed cat had gone on the attack.
Ugh, we just love her in purple!
There were actually a few instances when the wind threatened to rip the dress right off her, but Jess just smiled through it like a pro!
And we're just so glad photogs got this shot of her with one leg bared to show off her silver strappy heels. Perfect shoe choice for this dress!
