Tomorrow marks the annual Rittenhouse Row Spring Festival, during which more than 50,000 people descend upon the city (Walnut between Broad and 19th, and 18th Street from Locust to Sansom) for food, games, entertainment and—our fave part—fashion and beauty. It’s a da7y to turn it out style-wise—really, the entire city is out—but you need to be smart when choosing your outfit. Here, our 5 fashion tips for the all-day party. 1. A cross-body bag. It keeps your hands free for eating, drinking and shopping. Plus, it’s easier tote around through throngs of people. My recs:  Drum bag, $47.04 at ASOS,  Chloé Marcie bag, $1,395 at My Theresa,  Alexander Wang Rockie mesh small cross body bag, $695 at Bergdorf Goodman.
2. Shoes you can walk in. It’s crowded, and you’ll be on your feet all afternoon. You don’t want to be teetering around in uncomfortable shoes. Just trust us on this one. My picks:  3.1 Phillip Lim Ferdinand open-toed bootie, $592 at Joan Shepp,  Loeffler Randall Tiger Dot flats, $175 at Peter Kate,  Chiara Ferragni Spaghetti Kiss denim loafers, $211 at Luisaviaroma.
3. SPF! Just because you’re not at the beach doesn’t mean you can’t score a serious sunburn at the Spring Festival. Keep your skin safe (and wrinkle-free!) by slathering on any one of these awesome sun-proof creams. My picks:  Trish McEvoy Beauty Balm Instant Solutions tinted moisturizer, $85 at Bluemercury,  Dr. Dennis Gross Sheer Mineral Sun Spray, $42 at Rescue,  Avene SPF 50 Tinted Compact, $34 at Beans Beauty.
