Need help choose a dress?

I found three dresses for a party, which one is best?
1# ASOS Crochet Trim Maxi Dress (black)

2# Chiffon Beading Sleeveless Modest Prom Dresses (blue)

3# A-line Chiffon One-shoulder Long Prom Dresses With Rhinestone (purple)

It depends on what type of party it's for

With the first image of a party which pops into my head; I wouldn't go with any of those dresses. They all seem a little formal. As @Vas Happenin' Crazy Mofos has said; it depends on the kind of party though.

I like the ASOS Crochet Trim Maxi Dress. But it'd be a better pick if there was more info about you. (Height, shape, color (Skin) , and the type of the event)
