I only had one "real" Barbie doll. I mostly had my sister's hand-me-down "Fat Tammy" dolls. Tammy was slightly more plus size than real Barbie and when I tried to squeeze her into real Barbie clothes the seams split.
You would have thought this would have traumatized me as a child and made me not gain weight but it obviously had no ill effects on my eating patterns. ;)
I used to stage elaborate scenes where my only real Barbie with her skinny bitch temptress ways would steal Fat Tammy's boyfriend away... who come to find out from searching on eBay was actually Fat Tammy's brother Ted.
I soooooo need therapy for that one.
