Literally the most iconic long sleeved shirt ever, super rare and one of a kind! Its from the brand free people in a size XS, it can fit xs perfectly fine with a casual look it can fit a small perfectly fine too, i usually wear size medium and thats when this was a bit tight on me so I’d recommend this for sizes xs-s. Its the exact shirt kim kardashian wears in the iconic bag scene, just in the multicolored blue/gray chevron color pattern :) to note there is some stretching in the material around the chest area where it looks like there are micro holes shown in last pic. Beware that they might actually become holes if you over stretch it, so I recommend to hand wash and dry this piece to preserve it. Or you can always try to stitch it up as a preventative! When worn its not really noticeable if what you’re wearing underneath is the same color as the top.
