Sexy Stars: Kim Kardashian suffers wardrobe mishap in NYC

Oops!

Kim Kardashian has been showing off her sexy bod post-weight loss in revealing styles -- and the reality star suffered a minor wardrobe malfunction in NYC as result of her unbuttoned henley tank! (Similar tank here.) The mother of two totally stunned in white cutoffs and a floor-length duster -- but her shirt flew open revealing a nude bra.

Speaking of va-va-voom ... Charlotte McKinney put on quite the display when she slipped into a form-fitting brown leather bustier dress for a night out with a similarly-clad pal. The frock's sexy cut totally highlighted the model's bombshell curves. (Similar dress here.)

Actress Emma Stone went a different route than her A-list counterparts, opting to say more covered-up in a '70s-inspired green floral minidress with on-trend bell sleeves and a contrasting pink bodice. Mustard yellow ankle-strap pumps completed her gorgeous ensemble. (Similar dress here.)
