Nothing welcomes the warmer weather like the perfect summery dress, but being on-trend doesn't have to break the bank. That's why we rounded up the best options we found under $100. We love the polished effect of the blush-toned shift by Warehouse, and Zara's tropical print is ripe for wear at a shoreside party. Or, channel your inner Jennifer Lopez with the glamorous white option by Mango -- we could definitely see Jenny from the Block sporting a similar style!
