Make no mistake about it: at 4'11" and 88 lbs., Kristin Chenoweth is a petite star.
"I never really think about being short or a shrimp until someone goes 'You're short!'" she tells PEOPLE. "But it doesn't offend me too much."
Still sometimes trying on clothes is the ultimate reminder that Chenoweth – who normally wears a size 0 or smaller – may not be built like most other 42-year-old women.
"Occasionally I will shop in GapKids," admits Chenoweth. "I can wear a size 12/14. It's kind of fun."
The one shopping experience that is not child's play to the singer-actress?
"Shopping for a bikini for me is like it would be for a lot of women in America: hell on Earth," says Chenoweth, who showed off her slammin' figure in a Victoria's Secret bikini in the latest issue of PEOPLE. "I'm a 32C on top. I have curves! I'm not a stick, so the wrong suit can make me look squatty. I have to watch that."
No matter what she's wearing, there's always one accessory to all her outfits: high heels.
"Being petite, a little goes a long way," she says. "I came out of the womb with heels. I will die with them on. I also like wearing heels in a bikini!"
