Product content

First of all, sun protective fabric. Next, the fit. Long in the sleeves for my 5’11” body. And not see thru fabric! Love it for the Arizona heat!

I love the hemline of this top, it is super flattering. I also love that the boatneck isn’t too wide. It shows off my collarbone without showing off my bra straps. The fabric is light and soft. Size is a slightly relaxed true.

Reviews

Flattering!

"I love this too! It has a very flattering cut! Runs true to size, not tight fitting."

Tracy P. (5/5)

Too Big

"This top was 1. 5” wider than the same top ina different color."

Robin B. (3/5)

Just Right

"Fits well and looks good."

Robin B. (5/5)

Side split shirt

"I liked my blue one so much that I ordered 2 more—one black and one white. Great fit and launders easily."

Suzanne H. (5/5)

LIKE? NOT SO MUCH.

"The neckline is lovely. Other than that, it is rather unspectacular. What could be a graceful side of the garment leaves it bulky, bumpy and shapeless. That you are now stitching the white logo on the garment rather than the beautiful embroidered logo is a shame. I also bought a Morada tee in the magnificent Eden green. WHAT HAVE YOU DONE TO MY TEE? The neckline change from the crew with the simple piping is no more? The new crew neck is common and almost a mock turtle. And, again, with the sewn on white logo. No longer a fan of the Morada.

Flattering - more colors please!

"I have this in 2 sizes. The small is great with joggers, shorts, skirts or other pants. The medium is fantastic over leggings because of the extra coverage. This style is so much more flattering from all angles than a basic straight hemmed tee. Highly recommend. 5’6” 132 lbs"

"See above review."

Suzanne H. (5/5)

Runs too small

"I don't like this shirt. It is too clingy and has this spandex feeling. I'm thoroughly disappointed. I ordered two, and they are expensive shirts."

Kim H. (2/5)

Love it!

"Great color and the material is quality. Very comfy!"
