Can anyone help me with the size of this this item? It's the colorblock striped boatneck, it's an older item and a store that isn't local has it. I'd have to order it without seeing it, but it would be final sale.
I wear an XS in the vintage cotton line comfortably, and I know J. Crew tends to run big with some items. But other XS items sometimes have tighter arms on me, so I don't know about this. How does the size run? TIA!
