4 and 3/4 Stars
Color: White, Size: XX-Large
Plus: Fabric has heft and weight, soft, completely opaque, drapes well, and doesn't cling. Sleeve length is perfect and width comfortable. Neck size is comfortable. Dressy enough for an office work top. My bust is 1-2 sizes larger than my hips, but this top doesn't look too oversized at my hips. Minus: Hem is even with my wrists, I wish it was an inch longer. Wash inside out to avoid snags. Sewn well but they do skip the bias tape that covers the back neck seam on the inside of t-shirts.

Great buy
Color: White, Size: Large
Great T-shirt if you want something a little dressier than a regular T-shirt. Nice material and fit. Love the little bit longer sleeve.

Runs big size chart not accurate
Color: Black, Size: Small
I only put three stars because it runs large. Not a true small. I really wish they had xs. It's too big in neck and shoulders bunch up. The fabric is thick and not at all see through. I like the high neck and half sleeves. The fabric feels soft but also kinda "slick" so some people may not like that feel. For reference I'm barely 5ft and 115 and the small is too big. Not sure if I'm going to keep it or send it back. Price point it is a nice shirt
