What to wear to a poolparty?

If you have an uber cute bathing suit, feel free to wear something a little showy, like a cute cotton dress or loose off the shoulder shirt with shorts(not booty shorts please!:P). You'll attract better attention looking cute and summery than like a hoochie. I am not sure if by no bikini you mean a one-piece or just a modest two-piece... but either way more power to ya! As for make-up.... go light. Maybe a little waterproof mascara and bring a bottle of moisturizer or sunscreen to keep your skin hydrated from the chlorine and sun. You can always do your hair all fancy because worst case scenario you decide to have some fun and get swimming and it gets wet and comes out. Worst case scenario with intense make-up is you get wet and have an ooey gooey mess. Whatever you wear probably won't stay on for long if you are going to wear your bathing suit so try going comfy for after the pool. Have fun!
