Anything you would like to! As long as it covers you (KSP doesn’t do bathing suit or boudoir photography) and allows you to move freely. Bright colors work great. Jeans are always cute. We love sundresses. Tshirts printed with logos and such usually do not work well, so try to avoid them. Solid colors, stripes, plaids, and flowers are always fun. Or stars! Don’t forget to bring along some accessories, too. We love the modern and punk looks you can get from the right necklace or hair fascinator. Check Esty for cute stuff if you don’t currently have any in your stash. We’ll also be able to see your feet in the photos, so make sure you remember to wear shoes if you like that look.
