Buy at least 2 sizes bigger than you need.
Color: Heather Grey, Size: Large, Color: Heather Grey, Size: Large
These shirts are pretty soft, you can tell they are different from other shirts boasting natural fibers. They don't compare to the thin or drape from onno shirts but its less than half the cost. I have ordered 3 more, but with that being said... the shrinkage was unreasonable. The shirt lost 4 FULL inches in length and a little over an inch in width. Now, taking into consideration that I am a full grown hobbit this shirt is unsuitable for anyone over 5ft tall. I this would literally be a crop top on a average size adult and it is a large! I'm going to test out 2 other styles and the xl in this shirt but holy cow i really want to wear it because it's thin and will protect me from the sun but it's way too small now. I really hate the feeling of dry fit uv protection clothing, and this is so much better. Just wish I could wear it and didn't waste 20 bucks washing a shirt I can only wear in the comfort of my own home in fear of being arrested for indecent exposure. I would estimate shrinkage is more than one size.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.
