Fabric Details
Aqua Classic™ FabricAqua Classic™ Fabric
This is where it all started! We set out to develop a superior UPF 50+ swim fabric that didn’t feel heavy or rubbery like scuba rash guards. The result is a technically elegant, sun-safe swim fabric that is chlorine and saltwater resistant with a modest 4-way stretch. It’s silky smooth on the inside with a figure-flattering matte surface on the exterior. Customers love our Aqua Classic because it’s lightweight, quick dry and comfortable.

Coolibar’s sun protective clothing is designed to be worn in the sun and to provide excellent UV protection. If you have any questions about size, fit or style, talk to one of our Customer Service Representatives at 1-800-926-6509. They'll be happy to help, as well as offer expert advice on coordinating sunscreen hats with your wardrobe.

Measure circumference of hand around fullest part just below the knuckles, excluding thumb. Use right hand if right handed, and left hand if left-handed. Measure hand in inches and refer to the sizing chart for your glove size. Use the larger number to determine your size. People with extra long fingers, or who would like a looser fit should consider ordering a size up.

PLEASE NOTE: 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 Soooooo versatile This was a complete lifesaver on our last beach trip. I wear it all the time as a swim shirt, but when it came time for dinner, I realized I didn't haven anything dressy enough. Coolibar genius to the rescue - I untied it, pulled it down, tossed on flip flops and wore it as a dress. I got compliments on my "dress" when I was just wearing it in the ocean just a few hours before. LOVE LOVE LOVE! I will never leave without this shirt, ever! Keep up the great work!

Rated 2 out of 5 by from That seam that others have mentioned I bought it last year in Medium. The lower portion fit fine but the top had that seam going right across the bust drawing attention to that area. . I ordered it again last fall in Large, figuring that would solve the problem but the seam still goes across the bust. For fuller figured ladies this is a poor choice. I even took it to my seamstress but she said nothing can be done about it. I am 5'6" 145 lbs . I was able to give my Large one to a friend ; still working on a new owner for the Medium.

Rated 5 out of 5 by from Perfect SUP top When I was diagnosed with Melanoma I knew I would have to cover up for my favorite water sport. This was a really comfortable outfit in the Florida Keys heat and humidity. Thank you Coolibar.

Rated 5 out of 5 by from Delightful As soon as I touched this Swim Shirt I was delighted. Then when I put it on I kept it on for hours and even considered sleeping in it because I liked it so much. Jk ;)) I showed it to my daughter and now she wants one! As to the construction, it is well made and has a nice zipper flap at the neck so the zipper does not cause discomfort. The fabric has a nice stretch to it so it is very comfortable. The cut is roomy so its not tight at the hips, which is often problem for me bc I am pear shaped. My daughter is slender and it looked cute on her. I think anyone who orders this shirt will be pleased.

Rated 5 out of 5 by from Awesome fitting I bought this about a month ago and it was awesome.... it fit very nicely. Not to tight nor too loose. I was able to die everything easily in it without feeling suffocated. Also, the material is so airy. It dried off with in minutes.

Rated 5 out of 5 by from Good coverage and nice fit This provided good coverage and a nice fit. The neck is too tight for me and I have to leave it slightly open to not choke but otherwise I love it.

Rated 5 out of 5 by from Good quality and comfortable I usually buy medium to get a modest loose look, I'm 4 months pregnant (140 lbs and 5'4") and i still have a modest look. Bust 36dd/ddd with still wiggle room. Prior to pregnancy I could have probably purchased a small (125-130lb) for a more snug fit. But no complaints.

Rated 5 out of 5 by from The best swim shirt out there! This is my second ruche swim shirt from Coolibar that I own and I LOVE it! The fit is amazing- fits all body types. The ties on both sides allow you to adjust the length, depending on your preference. They dry SO fast! They are high quality tops that are comfortable and modest! (which is a plus as a woman who wears hijab). Most importantly the SPF 50+ protects you from the sun! What more could you want? If you are debating buying this top- DO IT! It is worth every penny!

Rated 3 out of 5 by from Probably not the best for tall and/or busty women I plan to take up paddle boarding this year, so I got a couple of these swim shirts to protect me. They styling is very cute, but the upper seam cuts right across my bust, instead of being and empire-waist effect. It's not a good look, so I am returning. I'm bummed because it is otherwise a darling top.

Rated 5 out of 5 by from Perfect fit and color I bought this for a trip to hawaii and I was so happy with it. I wore it as a cover up and for warmth on a very chilly, windy boat ride. The color is perfect. The fit is just right for a medium (I am 5’6” 140).

Rated 5 out of 5 by from Great Coverage I bought this for a recent trip to Aruba. I needed good coverage from the strong sun, and also wanted to feel comfortable wearing it to breakfast in the AM, and lounging by the pool. I was absolutely protected from the sun. I also liked the fact that it covered my "behind." I highly recommend and would buy again! (I also have this product in 4 other colors/patterns).

Rated 1 out of 5 by from Sizing way off I ordered it for an upcoming trips. The sizing based on the measurements table is way off. I immediately sent it back with a request for a new size. I’ve heard nothing in return. It’s been two weeks.

Rated 5 out of 5 by from Love it! I love this purchase. It’s pretty and I can wear it long like a dress/cover up or make it shorter to wear as a shirt. It’s comfortable to swim in and wear as a coverup. I recommend it.

Rated 5 out of 5 by from Ruche Swim Shirt is AWESOME I absolutely LOVE this shirt!! It is simply beautiful and I am reluctant to delegate it to swim wear!! My husband likes it on me so too!! I have worn it twice over black legging and it look great! Exceeded my expectations, for sure!!

Rated 5 out of 5 by from Cute and flattering swim shirt! I am SO glad I purchased this for my trip to Hawaii. The size was accurate (I normally wear an XL, and the XL fit comfortably). There is no lining so I switched between throwing this over a sports bra or an actual swimsuit. I liked that the sides had drawstrings so I could pull down for almost a dress to cover my butt, or pull up to more shirt length. The shirt dried pretty quickly when I hung up or laid it in the sun, but I can’t say how long. Overall, I was VERY happy with this purchase.

Rated 5 out of 5 by from Love this swim shirt I finally got to use my new swim shirt. I am 61 years old and heavy. I love the coverage of this shirt with my swim shorts. I felt comfortable wearing this and not being self conscious of my weight and 61 year old skin! I bought the navy blue but plan to purchase the black and white striped shirt. Thank you Coolibar for making these for us "bigger" women who love the water too!
Date published: 2017-09-03
Rated 5 out of 5 by from Excellent! I highly recommend. I have bought 2 of these and have been absolutely happy with them. I burn easily and painfully. With these shirts I can swim again, I can be on the beach and in the water as long as I want. They look nice, feel comfortable, dry fast. If you are overweight, as I am, these shirts cover up the fat and bulges so you don't have to be embarrassed to swim. I only wish they included a shelf bra. Instead I wear a jogging bra underneath.

Rated 1 out of 5 by from Feels heavy and claustrophobic I just received this item in navy blue as well as the navy blue swim capris. I found that it felt very heavy and claustrophobic and I instantly felt very warm in the short time that I had it on. The seam under the bust is too high and the collar is very tight. Also, I was disappointed that the colour was not really a match to the swim capris which I really liked. I am reluctant to return them as I live in Canada and found that in addition to the US exchange and shipping/handling which I was prepared to pay, I was charged an additional $53.66 for customs which made an already overly expensive purchase absolutely outrageous. I am not willing to take a chance on more hidden expenses upon returning this item so I'm stuck with it.
