Everlane Uniform button down shirt

Everlane Uniform button down shirt. Long sleeve color is an olive, browny green Medium Minimal wear, in good condition. there's a very small mark on the front. The shirt has been washed but hasn't been worn for a while so I'm not sure what this is but should come out. too small for my husband so looking to make space. the model photos are from the Everlane website for their current Slim Oxford style which is very similar to this shirt.
