Overpriced for a cheaply made shirt. The hems are glued down, not sewn.
Color: Grey/Black Square, Size: XX-Large, Color: Grey/Black Square, Size: XX-Large
I'm not sure how well this shirt is going to hold up, but I'll give them it's lightweight and cool! LOL There's almost nothing to it, it's so light. Mrs Aloha Friday is really crafty, but doesn't do much sewing. It's like she made this shirt with those tapes that you use to hold a hem temporarily, with an iron. LOL She's now got the idea she can make me shirts herself by just gluing them together! ;o) Neither of us is sure how well this will hold up to multiple washes. I'll edit my review if it falls apart. I think the price is nuts for what you get, at $27 as of this writing. There are literally holes in the shirt! I'd feel better recommending it at around $10. If you need something lightweight, yet still an actual shirt, here ya go. The problem is, I'll need to wear an undershirt under this or I'll just sweat right through it in the heat, and it will show the texture of everything it rests against, like the hairs on my chest. Or worse, they'll poke through the holes! Gah!! LOL So sorry for that imagery. I got the Grey/Black square.
