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.

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 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!

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!

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!

Rated 5 out of 5 by from Great cruise shirt! We travel on cruises often, this shirt is a great addition to my "cruise wear". Never have to worry about being too hot, getting too much sun or being wrinkled.

Rated 5 out of 5 by from Navy - Classy Shirt I bought this for a weekend Rotary Meeting in the Virgin Islands and wanted to look smart during the casual events. It was perfect with white pants or jeans. It is a great topper for dresses and protects my sensitive skin from sun poisoning. Hand washed and line dried.

Rated 5 out of 5 by from JUST LOVE IT!! I bought this in the black geo print several months ago. I can wear it casual or dressed up. It feels wonderful to know I am protected ( I have Lupus). It is so comfortable you hardly know it is on!! Love, love love it.

Rated 5 out of 5 by from Totally weightless! Beautiful fabric! Light & airy, but it works as well as my other Coolibar jackets for blocking the sun and heat.

Rated 4 out of 5 by from Lovely, light fabric; great design The only issue for me is that the sleeve length is too short in a size small. I'd want the sun protection to extend at least an inch or two.

Rated 3 out of 5 by from Size confusion .... I loved the color I ordered (aqua) and the material of the shirt was soft and lightweight ... very comfortable. I used it as a swim suit cover up, too. Although I measured myself with a tape measure, I found that the shirt was too large for me. I did keep the shirt as I was traveling to Hawaii the next day and needed a sun protection shirt for the trip. I will order another shirt of a different color and the next smaller size. Hopefully, that shirt will fit perfectly.

Rated 5 out of 5 by from I love the color! I haven’t had a chance to wear the shirt yet but I love the color and the way it feels when I put it on. The fabric is light and silky feeling. I also love the length. I’m just waiting for summer like weather before wearing it.

Rated 4 out of 5 by from Very nice It’s terrific but the white is too sheer so I’ve returned it. I’ll buy it in blue. Love the light weight fabric & the length.

Rated 2 out of 5 by from Wrinkles Great lightweight shirt but it wrinkles. I have tried washing it and hanging it wet and it still looks like I slept in the shirt. Not great for travel.

Rated 5 out of 5 by from Chic! Comfortable! Easy Care Bought this for road trip. Easy packing. Washes easily. Flattering. Purchased a small for 5' 4.5" 130 pound frame: 37, 29, 39.

Rated 5 out of 5 by from Love it! I ordered a L but now I am ordering an XL. The L doesn’t closed all the way. So I am going to used with a tank top but for the night I want to be able to close it all the way. For reference I weight 195 pounds my bra size is 38 C and my waist 32. Overall great blouse!

Rated 5 out of 5 by from Absolutely beautiful shirt Haven't been able to wear this yet but have tried it on and it fit beautifully so I'm anticipating many years of wonderful use. The material has a luxurious feel and drapes very nicely. The color is to die for so I can't wait for our next vacation to wear this.

Rated 5 out of 5 by from Second one I bought! I bought my first one of these last summer. I love the neutral color and light weight. Great for summer. Wore it everyday. Decided I wanted a second as back-up. Will keep it at work for lunchtime walks.

Rated 5 out of 5 by from Beautiful I am 5’ 6” - 123 pounds and ordered an XS size for a trip to Costa Rica. The shirt fits well and is extremely well made with finished seams and attention to detail. The fabric is lightweight which has been a bonus on our daily walks on the beach. The difference between the SPF protection and the sun exposure on bare skin is noticeable. I will be purchasing another shirt or two and hope that the color options expand.
