Exactly what I needed-a good button down inexpensive shirt
Size: Large, Color: White
This is a nice heavier weighted button up. I bought this for me (female) & so far I really like it.

Fabric quality good, Size incorrect
Size: Large, Color: White
The quality of the fabric is good. I like it. Don't like multiple tags, where everyone is moving towards tagless shirts. I had to literally struggle with scissors to remove the big tags on the shoulder. Size wise its little tight-fitting than my liking for formals. I think one size bigger than the standard size would have been better for me. I suggest ordering one size bigger.

Surprising
Size: Medium, Color: Light Grey Vertical Stripe
It’s a heavier cotton, but like it very much will wear it in warm temps as well as colder. Was true to size and the small amt. of stretch makes it very comfortable. Shocked at the price,I purchased fully expecting a bit of dissatisfaction.

knocked 3 stars off because no shirt pocket
Size: X-Large, Color: Light Grey Vertical Stripe
Two stars because there's no pocket. Shirt is actually nice otherwise but I was so focused on finding shirts with button-down collars (so my Sony WXB400 headphones don't escape) that I didn't notice these didn't have a pocket. I always carry a fountain pen so I need that, also for my phone if I'm not wearing cargo shorts with a "technology" pocket. If pockets are important to you, this shirt should suffice. Price is right.
