Another AYR shirt! This one is a really light cotton popover in a size XS (but it's not super fitted, so a S could definitely wear this comfortably). It's brand new (bought last summer, never worn). It's a super clean-looking layer to toss on over a cami--it works equally well tucked into work pants or over shorts/skirt/what have you. $40 + shipping. alb2199 at columbia dot edu for questions.
