🔥 General sizing tip 1: For all swimwear, a snug fit on land is a good indication that it is going to stay on in the water. This is because swimwear fabric stretches and becomes heavier when wet. So if it fits just nice on land = loose in water. Fits snug on land = it’ll be okay to surf or swim in without you worrying about the swimsuit falling or slipping off.

🔥 General sizing tip 2: If you are purchasing with the intent to surf or do other sports & NEED it to stay on, choose according to size chart. Otherwise, you may choose 1 size up for a more relaxed fit to lounge or lightly swim in.

🔥 Sizing tip for ONE-PIECE SWIMSUITS: If your top is size S & bottom is size M, you may choose either S or M depending on what you’ll mainly use the suit for. For better hold = choose size S. For more relaxed fit = choose size M.
