01Sleeves, cups and a torso measurement
An athletic boyshort suit with a built-in bra that is the most-rated one-piece in the Ocean Blues collection, a shirred bandeau, a high-cut low-back, two ruched cuts on the plus run, three long-sleeve zip suits and a swim dress with shorts.

A one-piece is the only thing on this site that needs a torso measurement, and the fitting guide on the front page says how to take it. The Ocean Blues suits split by what covers the arm: the eight short-sleeved or sleeveless cuts, and the three long-sleeve zip suits people buy for a lake or a whole day out, two of them in a UPF 50+ fabric. Inside, the athletic boyshort, the two zip rash guards and the swim dress carry a built-in bra; the shirred bandeau, the slimming suit and the molded-cup zip suit carry a shaped cup; the molded-cup zip suit and the swim dress add a wire. The high-cut low-back is the cheapest suit here and the one with the least inside it. Sizes run S to 3XL, to 4XL on the long-sleeve boyleg, and two ruched suits are cut on the plus run.

Prices are the ones from our last update; the Ocean Blues approach updates them on a schedule, and the figure at the till is the one that counts.
05Before you order
What people want settled before they buy a suit.
One of the two long-sleeve zip suits in a UPF 50+ fabric: the boyleg athletic suit with a built-in bra and a run to 4XL, or the molded-cup suit with a stand collar. Sleeves cover the arms, the zip gets you out of it wet, and the rating covers the skin under the fabric while it is dry. Hands, neck and face still get sunscreen.
Yes, and it is the number people skip. Tape from the top of one shoulder, down the front, between the legs and back up to the same shoulder, snug but not tight, and hold it against the torso length on the chart for the suit. A one-piece that is right at the hip and short in the torso pulls at the shoulder all day.
The swim dress with shorts: a one-piece with a wire-free built-in bra and removable cups under a skirt that covers the top of the thigh, with shorts sewn beneath so that the skirt can lift in a wave without consequence. It is the most covered thing on this shelf and runs S to 2XL in four colourways.
