La Shirt Classica, Cotton Poplin

They make the best oversized button downs, period. I've tried some other reputable brands (Donni etc.) and nothing comes close to the quality and ease of Comme Si shirts. I love the way they drape and fit (I have a few sized up for an even more oversized fit, which is nice for summer months where I want to be covered up but don't want fabric touching my body haha).

This color is fun and Tibi ring-3'ish (IYKYK), but I have a few other colors that are more neutral and I love them all.

When I first started ordering from them the returns process was kind of clunky (email and wait), but I am happy to report they have solved that problem as they've scaled up.
