A lot of the brand dresses are sized best for women with about 32-36 bust and 24-28 waist. So they do tend to look great on those with a bmi of 20-22. But they were not designed to hold an extra 10 inches of adipose. Hams stretch the back shirring to max levels. But normal sized humans only use a couple inches of the stretchy panel of fabric. It is a design aspect as well as functional. I think whales are attracted to the child like sweetness and cuteness of the style. The over the top pastel candy adorable nature embodies everything they wish they were.  They like to pretend they are sweet and cute.  The thing is these hams don't even have waists. So they can't even get the shape remotely right. But any excuse to don a pastel wig and say look at me, right?
