Im not a fan of "club wear" as it just looks trashy. I think its even better, and classier, to wear a nice dress or classy, but still sexy outfit, that way you can go elsewhere after the club and you aren't limited by your outfit. Plus, some clubs aren't a big fan of the club-wear, unless its a rave or something.
you can't really go wrong with something that is lose and kinda drapes at your bigger spots and is tight at your smallest spot like for me my smalls spot is a few inches bellow my boobs so I put a belt there because it draws your eye to that spot making you seem smaller
I don't like that particular dress much. Maybe something sleeveless, but a smiliar style in terms of a cinched waist and not too tight so it's still show your figure a bit but not too much. Also, you can never go wrong with a bit of cleavage
leggings and a nice lacey top from forever 21 or h&m
