The ideal store fitting for a Blueseventy wetsuit is unhurried, dry, and cool. You want your skin and the suit to be clean and dry, the room cool enough that you are not sweating, and enough time to check shoulder mobility, torso length, and neck comfort. A rushed fitting in a hot store makes every suit feel tighter than it will feel in the water.
Arrive dry, cool, and lotion-free
Skip lotion, sunscreen, and body oil on the day you plan to try suits. Neoprene grips moist or oily skin differently, and those products can transfer to a suit you may not buy. Dry skin helps you judge the compressive fit of the neoprene, especially through the chest, torso, and thighs. If the store is overheated and you arrive sweating, wait a few minutes in the air conditioning before you try a suit. Sweat makes the suit stick and can turn a normal snug fit into a wrestling match.
Wear what you will swim in
Try the suit over a thin swimsuit, triathlon top and shorts, or a snug base layer that sits flat at the hips and shoulders. Cotton underwear or loose shorts bunch under neoprene and create false pressure points. The goal is to mimic race day as closely as you can without water. If you normally race in a one-piece or tri suit, wear that.
Give your shoulders a real test
Once the suit is on and fully pulled up through the legs and torso, reach both arms overhead, rotate your shoulders, and trace a few swim strokes. You are checking whether the suit restricts the catch or pulls down at the neck. A suit that has not been pulled high enough into the armpits and crotch will always feel short in the torso, so make sure it is positioned before you judge it. If shoulders restrict, check two things: the suit may be too small, or the arms may not be pulled up far enough. A suit that sits too low at the shoulders can cause unnecessary fatigue, so pull the arms fully up before you zip. A properly donned Blueseventy suit should feel snug on dry land and more comfortable once you are swimming.
Check the neckline and the zip
Ask the store staff to close the zip and check that the back panel lies flat. The neckline should sit against the skin without gaping or digging. Some suits, like the current Fusion, have a lower-sitting neckline for comfort without losing the watertight seal. Test how the neck feels when you turn your head to breathe and sight. A collar that forces your chin up or rubs at the throat will become the only thing you think about during a long open water set.
Narrow your size in store, then test swim
A good store fitting gets you to one or two sizes, but it does not replace swimming in the suit. Water changes how neoprene sits and moves, and the suit's buoyancy supports body position by lifting the hips and legs, which changes how a suit that felt borderline in the store feels after the first few hundred meters. If you are between sizes, choose the size that allows full shoulder rotation while still fitting snugly through the torso. You can try the suit in the water and still return or exchange it within 30 days if it is clean, dry, unmodified, and still has the tags and accessories. That policy turns a careful store fitting into a low-pressure first step. Find a dealer near you through the Blueseventy store locator, or ask the shop about a fit appointment. Happy swimming.
