Pack a denim mini with a white t-shirt or tank top and bright sandals for shopping days, and use a beach coverup that doubles as a sundress so that you can throw it on for post-sun fun. Invest in one quality, well-fitting swimsuit instead of several cheap ones that won't go the distance this summer. Instead of packing multiple handbags, beach bags and clutches for your every outfit, why not pack one that multitasks for every event? You can get a chic bag that goes from beach to evening in boho, straw and sleek styles, so pick one that works for you. A few inexpensive cotton sundresses will go a long way, and they're comfortable for travel. Grab a cardigan and carry it with you for chilly airplanes or cool summer evenings. Leave plenty of space to bring treasures from your vacation home.
