i'm not sure if the sale is still going on but most of the prom dresses were 50% off at bryan's bride at brentwood.
it's pretty cute. is it for prom or ceremony? i think it's good for ceremony but imo i think it's too plain and simple for prom. looks more like for a party or dinner.
how about these ones?

$110 (i have tried on this dress before and it's really cute)

$110? (i tried dress on this dress as well and i think it's 50% off at byran's)
it could be strapless or strap

$220

$125
if you're short, it's best if you get short dresses because you're going to appear shorter and stubby in long or poofy + long dresses. but long tight gown could make you appear taller and sexier.
