I have a large chest and it’s really hard for me to find button up shirts that are fitted through the waist, but also can button up all the way without having that awful gap between buttons. The shirt fits like a glove is very comfortable very well made and had a great price too. I’ll probably buy more other colors.

Lousy.

Fit Type: Regular Fit, Color: Light Pink, Size: Large

You should be ashamed. I received this shirt balled up and stuffed into a plastic bag. Literally. The shirt fit, but was so crumpled and nasty, that it went straight to the washer. Certainly not the first impression that Amazon Essentials wants to promote. The fabric seems nice. The fit was acceptable. The presentation was awful. I expect better. Edited to add: I like these shirts. I DON’T LIKE how they are packaged and shipped. My second shirt arrived today. It was packaged neatly in a plastic sleeve. The shipping sticker was slapped onto the plastic. No brown wrapper. Nothing. ANYONE walking past my porch could see my new shirt. Is this how you want to ship items?
