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 Perfect summer weight cover-up! Works with a bathing suit or capri leggings/tank top. The longer length provides great coverage. The sleeves are elegantly tailored making this tunic really versatile. Loved the olive, so bought another in navy.

Rated 5 out of 5 by from This is a perfect shirt! Love this blouse! Fabric is light and cool...perfect for hot, humid Texas weather. Roll up sleeves and a collar meet all of my needs in a top. Great length to wear with leggings and sandals. I have bought 3 of different colors and designs.

Rated 5 out of 5 by from Great shirt Love the fit and feel. Haven’t been able to wear it out and about yet due to social distancing. It covers all the important areas. Developing a sunscreen sensitivity so will need this more than ever.

Rated 4 out of 5 by from BEAUTIFUL The fabric is beautiful and light but I didn't like the length so I had it shortened by 4 inches keeping the side dirt.

Rated 4 out of 5 by from Great shirt. Shame about the static. Love this shirt (in theory - have yet to wear!). Print is fab. Could do with being a tad shorter in length (I’m 5’6”). More dress than tunic. Feels very silky but not sure how cool it will be once the temperature rises. Major problem with static. Shirt completely unwearable. Spent two days attempting to ‘ground’. It’s better but not sure what will happen when I try to wear it!

Rated 5 out of 5 by from New Mexico I bought this shirt a few weeks ago, and I now have packed it, for my next trip to New Mexico, up in the mountains. I think this shirt will work perfectly, over a pair of longjohns, and I could probably wear it the entire week! It folds into practically nothing, and fits perfectly over the longjohns, and though it is a bit loose without the longjohns, it can still work with leggings!

Rated 5 out of 5 by from AIRE fabric is simply the BEST to wear on HOT days On hot days I cannot wear anything but AIRE fabric. There is no other fabric that comes close to the lightness and comfort of AIRE. This top is great, from my experience patterned tops always look better in this fabric, because creases don’t show. I urge Coolibar to make a lot more clothes in AIRE fabric, NO other fabric comes close to this degree of wearable comfort in the heat. A loose wrap in this fabric would be fantastic!

Rated 5 out of 5 by from Can't say enough about this top! Just love everything about this Tunic. It's long enough to be a dress for me except for the slits on the side. I will mostly wear it as a swim coverup. the fabric is so soft and light I am amazed that it has suncreen! Previous fabrics have been much thicker and made me sweat in hot weather. I love the patterns...they are so flattering. Just love this top!

Rated 5 out of 5 by from Garment flatters the fgure. I like the design flow, but prefer a slightly denser material. Goes well with leggings and or tights. The brown would be more appealing in a deeper, richer chocolate brown color. I have the same style in black and want to purchase a second black medallion.

Rated 5 out of 5 by from Lightweight The tunic is great! I'm 175 (9"5) and I purchased it in size M. Usually I'm size S, but I prefer to go size up with my sun protection. +:The fabric is thin and breathable. -: It's more like a dress than a tunic. But it is still fine on me. However, I would be cautious if youre shorter than me.

Rated 5 out of 5 by from Keeps you Cool & Protected! I bought 2 of these shirts for my 2 week vacation to Egypt where it was extremely hot and I ended up wearing these the whole time. The fabric keeps you cool, reflects the sun, washes well and doesn’t wrinkle. I wore these like a jacket with a tank underneath. Highly recommend!

Rated 5 out of 5 by from Versatile and a dream for travel! I now have 3 of these and am very pleased. The medium fits perfectly - I am 5 feet 6 inches and about 145 pounds. The shirt washes in the machine and I hang it to dry- fast drying and non wrinkling and perfect for travel. . Also versatile because one can wear over. Tank or bathing suit...

Rated 4 out of 5 by from Lovely Print and Fabric Bought two of these tunics on sale and I am very happy with the feel of the fabric, the prints and the quality of design and sewing. I am not sure why they are so long -- too long for a shirt and not quite long enough for a dress. I plan to shorten one of them.

Rated 5 out of 5 by from Stay cool in the heat I have 3 of these and am about to order another... Love the long sleeve with roll up option...collar can go up in sun.... I am a skin cancer survivor, (melanoma, base cell, and squamous cell)... This shirt helps me to enjoy the sun and the out of doors. Always feel cool no matter what the temp!!! Love them!

Rated 5 out of 5 by from great fabric I really am enjoying this shirt. I can wear it over a bathing suit as a coverup (Im only 5 feet tall so it almost reaches my knees) or as a shirt when I try the ends up at my waist. Cool and soft on my skin. The extra small fits perfectly at 5 foot and 110 pounds.

Rated 5 out of 5 by from Flattering and feminine I bought a navy Santorini tunic- beautiful long shirt in a soft polyester fabric. Not see through. It will be working hard for me during our hot Australian summers during sun exposure times. Very happy with flattering fit, especially for tall women.

Rated 1 out of 5 by from Fits like a sack I love the idea of the sunscreen fabrics, and I really want to like the actual product, but so much of Coolibar is shapeless, and the sleeves and legs are too short. I had to return this item for that reason. I have other Coolibar shirts That I wear a lot, But only because I took them to a tailor to radically cut them down, and add fabric to the sleeves. It’s really expensive. A lot of the fabric patterns Look like old lady stuff So I always get the straight color.

Rated 5 out of 5 by from Elegant I love this shirt. It feels wonderful and flows beautifully. Originally, I bought the large and exchanged it for the XL, as I wanted it to be as versatile as possible. It is very long, so take that into consideration when purchasing.

Rated 5 out of 5 by from Soft & flattering I bought this in black. Very stylish and elegant, works for pretty much any occasion. More colors would be great.

Rated 5 out of 5 by from Very cool and comfortable in this heat I love in Miami and during the summer it gets very hot. These tunics somehow seem to reflect the heat; they don’t absorb moisture and or smells either. So I can wear it all day with sunscreen - in and out of the water- and it never smells or gets stained or smeared with sunscreen. And it actually feels cooler than any other sun or beach cover up I’ve ever worn. And then I wash and dry it and it looks brand new.

Rated 5 out of 5 by from Chic I bought this tunic in olive and liked it so much I bought the navy as well. It’s very chic, easy to dress up. Like all of my Coolibar clothes, it keeps me safe and cool!
Date published: 2019-06-13
Rated 4 out of 5 by from Great fabric, horrible choice of colors I love the shirt. I don't get sweaty biking to and from work in 80 degree. I love the protection the shirt provides. However, the choice of colors for most Coolibar products is horrible. It is either pale pastels or ugly prints. I cannot stand the pastels, so I bought this bright green with very busy print. My son asked me why I am wearing a shirt with fruit bowl design. :( I need the sun protection it provides, so I feel I have no choice. Why can't Coolibar use some solid bright colors? For example, the green without this horrible print will be great.

Rated 4 out of 5 by from This will be great for traveling I really wanted the white, but, as others have said, the fabric is too sheer. I purchased it in olive, which is a favorite color of mine. I think it will look great with white legging style pants. The other quibble is that the sleeve is almost too narrow for me to roll up. Another 1/4" would have been great!
Date published: 2019-05-13
Rated 4 out of 5 by from Stylish This Santorini Tunic shirt is beautifully constructed of Coolibar's wonderful fabric that I love. I purchased this shirt feeling it was more versatile than a shirt plus it affords more protective coverage. Unfortunately, since I'm short (5' 3"), the shirt came down around my knees. I ended up returning it. It would be great if you offered petite sizes. I have many Coolibar items, and am grateful for the products since I have skin cancer and do need as much sun protection as I can get.

Rated 3 out of 5 by from Love the shirt - too sheer in white!! I ordered this shirt in white and loved it - except that it is ultra sheer. I would like to wear this in the summer but am not putting a cami underneath. I would pay a little more for fabric that is not see through. Disappointing.

Rated 4 out of 5 by from Beautiful color I brought this tunic about a month ago. It has all the Coolibar sun features and the color is bright and upbeat. It is definitely long for me but it is a tunic!
