The deal is this kind of dress is sometimes overpricing (remembering it will only wear once). But hey, better to spend money on that occasion, than getting bullied by environment, lol.
The only thing you can do is to manage your budget.
I mean, we can choose expensive dresses for very special occasions such as your relatives wedding party, relative’s engagement or whatever makes you meet with your big family is need special treatment.
And for the middle to low range dresses are for events that you only can wear dress once, but you still really need to look glamorous, cute, outstanding without people notice that your dress is not that expensive :p such as prom night party, cocktail party and so on. Well in this case especially cocktail party, since it happens in such a sudden and no regular date.
