My 21 year old cousin is a tiny thing. Size O, and 24 waist (and thats loose) she asked ME where she could find some clothes on line. Uhm...I wear a 10 on my good days and 12 on the bad. Since Im the shopper in the family she thinks I can help..well, I have no idea. I was a size O at birth. Any ideas?? She is a trendy gal..(grail tshirts, 7 jeans, little sundresses,)you get it...Any ideas for me to pass on to her?
