Plus size models need to be healthy and fit. Plus size lingerie models still need to look great in their underwear - curves are great, but if you want to be a plus size lingerie model, the curves need to be in all the right places. If you are interested in becoming a plus sized lingerie model, start at the gym! Tone your waist, arms and legs but leave your hip and bust curves in place. You will be on your way in short order - and you'll be getting healthier to boot!
