I was pretty bummed when I had to return this one.
Sizing up was the move, the slim fit does require some wiggle room.
The sleeves though were about 6" too long (even when rolled to show the inner cuff). There was almost an extra 1" of fabric around the forearms, which made them feel baggy and loose, not very slim-fitting. The length of the sleeves extended past the bottom of the shirt. I've never seen any long-sleeved shirts with that disproportionate ratio before.

This is my new favorite shirt

All my other button downs I bought medium and they fit decent but were just kinda tight at the pits but I sized up to a large and it fits perfect! Great shirt

Inside and out. Great color scheme. Super comfortable and high quality material.
3 compliments in the first few hours of wearing it shows other people like it too!
It's my nee favorite shirt.
Pairs rather well with rose gold / black accessories.

This is my fourth button down from Threyda and by far my favorite! They just keep getting better!
