What to Wear to Every Outdoor Summer Event on Your Calendar

For a picnic in the park, and the potential activities that come along with the event, shorts and sneakers are a must. Instead of a casual T-shirt, take your look one step further by opting for a pajama-style button-down and mirrored aviators.

Outdoor concerts are the best excuse to slip into a romper or playsuit. Dressier than traditional shorts, the versatile one-piece is better than a dress at cutting down on wardrobe malfunctions when dancing. It even leaves the door open for a little crowd surfing!

For summer engagement parties, easy glamour is the name of the game. A printed dress will do most of the styling work for you so you can focus on celebrating the happy couple. Slip into a pair of high-heeled sandals, grab a matching clutch, and it's time to hit the dance floor in full force!

When your friends invite you over for a barbecue, use it as an excuse to break out that preppy summer shirtdress and ballet flats. Reach for a cross-body bag to keep your hands free for the hamburgers and fries you're already salivating over. Last but not least? Have a bit of fun and top the look off with a straw hat.

A pool party is the best time to rock a one-piece bathing suit. Doing double duty as a shirt and swimsuit, the full-coverage piece pairs easily with jean shorts when sitting poolside but cuts down on extra layers when you're ready to jump into the water.
