Do This: Sundresses on the Green Not That: Bikinis on the Green are, simply, tacky. Either you have the body for them or you don’t; either way, you should wear clothes on campus. Here’s How: Save your swimsuit for the beach and throw on a playful sundress like the Broderie cup sundress ($70) or splurge on this Marc by Marc Jacobs printed jersey dress ($200). Then we won’t laugh at you.

Do This: Flats and Short Shorts Not That: Look, we know Uggs are comfortable. But we also think they’re heinous. There’s no need to show them off by pairing them with shorts. With warm weather finally arriving, we motion for a pair of cute flats to complete a springy outfit. Here’s How: Instead of the furry clunkers, try Steve Madden lace-ups ($69.95) or Sam Edelman metallic ballet flats ($115).

Do This: Flirty Heels Not That: If you’re aching to show off a perfect pedicure, avoid the temptation to wear prom-like heels. Candy colors and thin straps just don’t look modern. Here’s How: We love funky wedges — they’re both easier to walk in and sleeker than their thin-heeled counterparts. Both the Nine West Getby ($79) and the Juicy Couture Cody ($198) are great options to take you into summer.

Do This: Top-to-Bottom Consistency Not That: Even though the weather can be a little iffy these days, stick to one season when getting dressed. Pairing your favorite summer shorts and sandals with your North Face fleece is a major style fail. Here’s How: Top off your outfit with a lightweight sweater, like Anthropologie’s Stretching Days cardigan ($78), or a surprisingly in-again denim jacket, like Gap’s model ($69.50).
