I don't have XS in those
I only have S. The S Dottie Halter runs kind of small though. It's almost "cropped". It might work. I measured them:
Dottie Halter-
L=7"
G=14"
N=10
DJ Tank-
L=8"
G=13"
N=9
Let me know if you think they'll work. If not, I'll see if we have any XS left - or any other cute stuff in XS.
