Rated 5 out of 5 by from Elegant comfort and protection The fabric is light, airy, and cool as it protects! I love the abstract print. I’m short enough (5’2”) that I can wear this as a dress.

Rated 5 out of 5 by from Beautiful tunic I love this shirt. It's comfortable and versatile. The fabric is easy care and perfect for travel.

Rated 5 out of 5 by from Elegant sun protection This tunic feels like silk and drapes beautifully. It is chic enough to wear out to dinner, or as an open top over a T-shirt.

Rated 5 out of 5 by from My New Favorite Day-To-Day Shirt! My new favorite day-to-day shirt! After my first, I bought three more! I would LOVE to see a "regular" length design in this very same product. So comfy, lightweight and soft--it's perfect for summer days.

Rated 5 out of 5 by from Super nice blouse but order a size up This shirt is great-lightweight and soft, washes well, and about thigh length which I like. It runs small though-I’m about 5’4 and weigh 104 lbs. and usually I order the smallest size in most things, but XXS was a tad snug, XS was perfect.

Rated 5 out of 5 by from Beautiful fabric and color. Soft silky light weight fabric in a great length. The sea crystal color is very pretty.

Rated 5 out of 5 by from Lovely silk-like material, very chic lines Love this tunic top. Use as a top with shorts, pants or a skirt. Also great as a beach coverup
Date published: 2021-08-06
Rated 2 out of 5 by from I did not like it Material reminded me of a lab coat so I returned it. Size small in other styles from this company fit me well but this style runs a little small. Color is pretty though, so that’s why I gave it 2 stars. I ultimately ended up returning this item.

Rated 4 out of 5 by from Tunic shirt It’s very long. Just wish it was 3” shorter or choices in length

Rated 5 out of 5 by from Favorite new shirt Comfortable. Cool. Very stylish, got lots of compliments. Wore as a bathing suit cover. Love!

Rated 5 out of 5 by from Dressy, silky fabric The silky fabric makes this shirt a bit dressy, so it's great for work. I love that the sleeves can be rolled up and secured with the strap that is sewn on. I have this shirt in five different colors and hope to see more colors in the future. I had to iron it to get the creases out and it may crease a little too easily, but that is the nature of this kind of fabric. After I wore the shirt and washed it for the second time, it didn't hold the creases as much. I keep it on a hanger rather than folding it, which seems to help. This is a great weight for late Spring, Summer and early Fall.

Rated 5 out of 5 by from Santorini tunic shirt. Very lightweight and comfortable to wear in very warm weather. And the color is perfect! And I especially like tunic length shirts WITH POCKETS!

Rated 3 out of 5 by from Nice shirt but not for me Shirt is too tight across my shoulders so I had to return it.
Date published: 2021-07-16
Rated 5 out of 5 by from Essential brilliant piece I bought this shirt in white about 6 weeks ago and have found it such an essential and versatile piece. I've worn it in the hottest weather to a party as a big shirt, on-line at professional meetings under a blazer (who sees the length?), on a camping trip and to the beach. I'm tall so I really appreciate the length, and it can be made shorter with a sash or beaded belt. Will definitely buy another. Please don't change the design. Wish it came in traditional powder pink, fuscia, etc.

Rated 5 out of 5 by from Glamorous cover up Beautiful, flattering, and protective! Washes well and can tolerate various stains. I’m a 6 and the S is a close cut but I wanted a tailored fit, if you prefer loose I would size up one from normal size. It’s great for chasing around my toddler at the beach or pool

Rated 4 out of 5 by from Love the Fabric, a little too long Love the Fabric, a little too long, unfortunately I am only 5'3" and this tunic seems a little too long, I will wear it because I love the fabric. Wish it came in a petit size. The fit is good around bust and hips.

Rated 4 out of 5 by from Improvement on Santorini Tunic Shirt LOVE, this tunic...but the arms are a little tight on me...makes it uncomfortable. The dresses fit perfectly and I love the feel and fit of them all!
Date published: 2021-06-24
Rated 3 out of 5 by from Easy to see through I love the colors. The style is classic. But I sent it back because it was a little too see through.I could see my bra pretty easily.

Rated 2 out of 5 by from Too long. Petite sizes needed. Pretty but very very long. No petite sizes available. I will buy a similar item from another company that offers petites.

Rated 5 out of 5 by from Gorgeous! I bought three full sets of matching Santorini tunic shirts, the wide leg petra pants, and matching sleeveless shirts in black, leopard print, and a funky brown print. Love them all and I get soo many compliments. They are soft, flowing, and very elegant.

Rated 5 out of 5 by from Comfortable and Slimming! Wonderful length and slimming style, comfortable, cool
Date published: 2021-06-07
Rated 3 out of 5 by from Too see through to wear alone I loved the feel of it, but when I put it on, even with a nude color bra, I could see bra and skin. Not the look I was hoping to wear.

Rated 5 out of 5 by from Great for the beach! I purchased this tunic a few months ago to wear on a trip last week, and I absolutely LOVE this tunic, especially for a beach cover-up. I received a compliment about the style, and it's super comfortable. I found the fit to be generous so it was perfect to wear over my swimsuit and even into a convenience store after the beach. The material is a bit thin, but for me that was perfect for how I was using it. It has held up through several days at the beach with salt water, sand and sun; and through several washings--and it always air-dried super quick and looked great with no ironing. In fact, several times I stuffed it into a beach bag, and it still came out looking great.
Date published: 2021-06-02
Rated 3 out of 5 by from Thinner than expected Unfortunately I had to return this. I went by the measurements in the size guide and a medium was too large. It's a lovely soft fabric but too transparent for me to wear without anything under it so I won't be reordering a smaller size.
Date published: 2021-05-27
Rated 5 out of 5 by from Santorini tunic shirt The length of this tunic is great for wearing with leggings, and the aire fabric is very lightweight and silky! I don’t know how I would survive a hot day in the sun this summer without it! I plan to wear it as a “jacket” with a tank top under it (also Coolibar) so I can take the tunic off when I’m in the shade or inside. The pink bloom color is gorgeous!
Date published: 2021-05-19
Rated 3 out of 5 by from Runs small This shirt runs small, hence the 3 star rating. It would be helpful if Coolibar standardized their sizes so that a large in any shirt was comparable to a large in any other shirt.
Date published: 2021-05-13
Rated 5 out of 5 by from A staple in my wardrobe! Originally bought this shirt in white, at a gift shop while one vacation 3 years ago. I wore it to death!!! Just replaced it and bought the olive green colour as well. I typically wear it with leggings. It’s lightweight and washes easily. It’s perfect for spring/summer/fall weather. I wear XS - 5’6” and roughly 125-130lbs.
