I want to look like the women on red carpet? i don't make much but could buy 2 gowns. should i?

Probably not: Those women usually arent very happy, and spending money you may need for other things will give you momentary satisfaction, then more anxiety about things you should have spent money on. Try on the gowns, take pictures in them in the store, and you will probably get the same satisfaction. If you still want them a month later, and are sure you can afford, go ahead.
