Not everyone can drop serious bucks on a dress for prom (especially since you’re going to most likely wear it just once), so here’s five places you can scoop up a prom dress on a budget .

eBay: The online auction site is still is a good option for finding prom dresses on for under $100. Make sure to get the full measurements of the dress (clothing on eBay are often measured flat versus on a person/mannequin) and ask to see several high res pictures

Junior Leagues Thrift Stores: The key to purchasing a prom dress at a thrift store is that the dress shouldn’t look like you “purchased it from a thrift store”. Junior League, a national women’s volunteer organization, Thrift Stores tend to be located in wealthier neighborhoods and often have higher quality dresses (including a nice selection of vintage prom dresses). The prices can be a bit high (at least for thrift stores), but you can and should try to negotiate a lower price.

Cousin/older sister closets: Raiding the closets of a family member or close friend is great way to get a “new-to-you dress” without spending any money. If you’re going for a vintage look, you might want to even look into your grandma’s closet (yes, I know).
