Dalizza before

2 of 12
Dalizza says her "juicy, healthy, happy butt" has always made it difficult to find a great fit. Dalizza usually buys larger sizes that fit over her hips, which leaves lots of extra room around the waist. Stacy thinks Dalizza is on the right track. "You can't fit the smallest part—you've got to start with the biggest," she says. "Everything else can be taken in [with alterations]."

The size on the pants label is just an approximation, Stacy says. Tailoring clothes to fit your curves is key!
