You can't wear the same frock to every fête. You're going to need more than one of these lovelies, and buying party dresses that are sensibly priced is just good smarts. Yes, you can mix things up with a fun blazer, a statement necklace, and various patterns of tights. But the dress is still going to be the focal point of your party look. Below, shop our favorite party-perfect dresses, none of which will run you more than $200. (And most are a lot cheaper than that). Let's party.
