Anywhere with Jcrew style gingham shirts that are smaller than Jcrew XSmalls?

Ok, so I'm small. Really skinny (135, 5'10), and Extra Smalls at Jcrew are still a tad too big on me. Anyone have any advice as to places where I can go where they have similar shirts at sizes just smaller than JCrew X-Smalls, for around the same price range? Thanks!
