Everlane The Viscose Knit Crew, in Navy Small NWOT

I tried on the white version of this and realized that I got the wrong size. I haven't opened the navy package - new with tags. Everlane's description: This piece features a slim fit, crew neck, long sleeve, wide rib texture, and slits at the side seams for comfort, in a blend of viscose stretch + recycled nylon.
