I always order girly AA mediums, and they usually fit fine, besides the fact that no two sizes are exactly the same.. You know how AA is. Order 2 of the same size and you get one that's bigger and one that's smaller.
But anyway.
I was planning on ordering the I Heart Threadless tee just to see how the new girly shirts fit, but decided against it after reading how short everyone says they are. I want a shirt that's long and fitted please (including the chest area). Not short, baggy, boxy, or has the tendency to bunch at the waist.. or feels paper thin. or.. well yeah you get the idea :P
