The measurements on our size chart are very similar to most major clothing companies. However, we generally allow for a relaxed fit - geared for outdoor activity, travel or a casual outing. Pants, skirts, blouses and polo shirts have extra room for comfort and are not body hugging. 

When fitting jackets, cover-ups or any outerwear, our fit model is wearing the appropriate under layers that we would expect you to be wearing. You do not have to "size up" - we have done that for you. 

Never try to measure yourself. Seek the help of a companion and use a soft tape measure. 

Height: Stand in stocking feet, with feet together, back to the wall. Measure from top of head to the floor. 

Arm: Bend arm to 90 degrees. Place hand on hip. Start at center of back of neck. Measure across the shoulder to the elbow and down to the wrist. Number of inches equals your sleeve length. 

Bust/Chest: With the arms relaxed down at sides, measure fullest part of bust/chest, keeping tape parallel to floor. 

Hip: Stand with heels together, keeping tape straight and parallel to the floor. Measure around fullest part. 

Neck: Measure around base of the neck (the lowest point of the neck). Number of inches equals the neck size. 

Inseam: Take a pair of pants that fits you well. Measure from the crotch seam to the bottom hem. Number of inches equal inseam length. 

Rise: Start the tape at the center back waist, run the tape between your legs, pulling comfortably at the crotch and up your natural waist. Total measurement is your rise. 

Waist: Measure around your waist, against your skin (not over your shirt or pants) at the height you normally wear your pants. 

Head: Measure around your head, from the center of your forehead, keeping tape straight and parallel to the floor. Measure around fullest part.

Rated 5 out of 5 by from Nice fit. I purchased a Medium swim bra, as I am normally a size 10-12 and 36D and weight 135lbs. I had to exchange it for a large. The fabric is nice, works well and I feel no need for a cup insert. The bottoms I ordered to match fit me in the Medium size. Thank you for making shopping and exchanging so easy, Coolibar. Now I am saving for the sun dress!

Rated 5 out of 5 by from Really comfortable! Some time ago I bought this 1 size smaller and it fit around the chest but the cups were a little bit small. When I read that 1 size larger was the same chest size but the cups were a bit larger I decided to try it. Sure enough the cups are better and even though the chest size is a tiny bit larger it still works really well and is even more comfortable than the smaller size. But the truth is they really both do work. Very happy with these swim bras for deep water aerobics!

Rated 5 out of 5 by from Great swim top Great top. I am an athletic middle age woman, 5'6", 132 lbs, and bought a M size. It fits great, just the right amount of tightness to stay on but not get baggy when wet. I also bought the matching briefs -- but got them in an XS. I first bought the S but they were too big, so exchanged for XS, perfect!
