Perfect "To Go" Untuck Shirt for all summer events!
Size: XX-Large, Color: White-all White
LOVE LOVE LOVE this shirt! Great quality. The material is soft and just thick enough to not be see-through but cool for our Southern summers or tropical locations. The only thing I would say is depending on your arm to shoulder size, you may want to go up a size. I originally bought an xl for my husband, but it was a little snug at arm hole area, so we exchanged it for a xxl (it is designed so you do not have to tuck it in so the xxl fit and looks great.) I reordered in the blue also. Excellent for weddings, dinner, outings etc.. definitely recommend!

Nice and comfy, light duty and feel great.
Size: X-Large, Color: Light Green
What they may lack in "durability" i.e. very light and thin = not going to last all that long, they make up for in fit [yes even for wide shoulders], comfort and style. If you want them to last, suggest a gentle cycle and just take ot easy on them. They are light, thin, and airy. Nice summer shirt.

Nice shirt
Size: Medium, Color: Light Green
The shirt is true to size. I'm 5'10" and 160 lbs. and the medium fits well. It is light and airy, and after light pressing holds its shape well. The little cuff on the sleeve is a nice touch. Be aware that the buttons are hidden (if that's the look you're going for). I can't speak to durability as I have only worn it once. I have several Coofandy shirts and they are all nice garments.

Great for the price
Size: Medium, Color: Grey
Nice and light material. Looks good. Suitable for hot temperatures and casual attire. The only thing I've noticed so far that isn't so great, is that the buttons are rather cheap and the middle part broke out on a few of them. Expect to resow some buttons. Otherwise great
