So i'm trying to figure out what to pack for our upcomming trip/etc. One thing i wasn't sure about was a swim suit cover up. Do i REALLY need one???? OR...can i just get away with throwing a t-shirt and shorts on or a sundress over my swimsuit? What do ya'll think? I found some cheap ones at Target and Old Navy for under $15-20. Is it worth if if i'm going to be at a water park all day or can i get away with just a t-shirt and shorts? What do you normally wear to a water park/beach setting when you need to cover up a bit???
