Low-rise jeans are a plus-size teen's enemy! This style of jean often causes unsightly bulges in all the wrong places --- think “muffin top” and weird hip bulge. Instead, look for at waist jeans that sit right at your waist. The right fit it also important. To keep a trendy look, buy bootcut, dark wash jeans. Dark denim looks great on plus-sizes and wears well with just about anything.
