I feel a little silly asking this, but I have no clue what makes sense to wear to a waterpark I am going to next week, as such activities are not my cup of tea - I am not sporty, am very clumsy, a lousy swimmer and burn in 5 minutes even with super high SPF. I am going with a large group of friends, and the activities are going to be water slides, then picnic and finally mini golf (which I have also never done).
Of course I get that this is super casual, so I was going to wear something along the lines of denim shorts/knitted top/flat sandals and a hat; but it is the waterpark part that confuses me. Do people usually wear their swimsuits underneath their regular clothes, and then remove the clothes to go on the water slides? The only bikini I have is 7-8 years old and hasn't seen the light of the day in at least 5 years, so I may have to go hunting for something appropriate at H&M. Also, should I bring some plastic flip-flops ( I own none)?
Thank you for helping clueless me and please do not laugh too hard at my ignorance
