What to Wear to a Water Park as a Plus Size Woman (Ideas)
Short answer: Wear a swimsuit that stays in place on slides and gives you the coverage you want, such as a boyshort tankini, a sleeved one-piece or a swim dress with built-in shorts. Add water shoes, a hat and an easy cover-up for the lines.
A water park means stairs, slides, wave pools and a lot of sitting on wet ground. You want a suit that feels secure and a little forgiving, so you can stop thinking about it. Here are nine full outfit ideas built around suits we sell.

Sleeved zip-front one-piece for slide days
Slides, stairs and lazy rivers all go better in a suit that stays put. This black long-sleeve one-piece has a front zipper, white side stripes and a short boyshort leg, so there is less fabric to adjust on the way down. Wear it with water shoes or slide sandals, a wide-brim hat and a loose tank as a cover-up in the lines. The sleeves also cover your shoulders and arms, which is handy on a long sunny day. Check the size chart and size up if you like a roomier fit.

See the swimsuitHow to choose a water park swimsuit that stays put
Think about how you will move. Slides and wave pools favor suits with fixed straps, full-coverage bottoms or boy shorts. Tankinis are practical if you want easy bathroom breaks, and swim dresses with built-in shorts give you a little skirt for comfort. Sleeves cover more skin in the sun. Before you leave, do a quick test at home: squat, reach overhead and sit down. If everything stays where it should, you are ready. Our size charts list measurements, so measure yourself and compare before ordering.
What to pack besides your swimsuit
Water shoes or secure slide sandals protect your feet on hot pavement and wet stairs. Bring a hat, sunscreen, a dry towel, a waterproof phone pouch and a tote for your things. A light cover-up makes lunch lines more comfortable. If a suit is not quite right when it arrives, email us within 30 days of delivery for a full refund. Return shipping is free. Shipping to the US is free and takes 7 to 14 business days, so order early for a planned trip.

Questions, answered
Is a one-piece or a tankini better for a water park?
Both work. A one-piece stays in place on slides, while a tankini with boy shorts is easier for bathroom breaks and still covers your midsection. Choose whichever feels more secure when you sit, reach and climb.
Can I wear a swim dress on water slides?
Yes, a swim dress with built-in shorts is a comfortable choice. On fast slides, tuck the skirt in front of you as you sit so it does not ride up. Check park rules first, since some parks restrict loose items.
What if my swimsuit does not fit when it arrives?
Email us within 30 days of delivery and we will refund you in full, with free return shipping. Our size charts list measurements to help you choose before ordering.
