Secret lives of Mormon wives star Demi wears a pair of jeans that are waist-defining, leg-lengthening obsession. This fit will show off your figure and make you feel as amazing as you look. The best part? They feature an ultra-flattering, vintage-inspired bell leg silhouette. Size Tip: For Levi's Ribcage jeans, most sources recommend sizing down one size, as the denim (often rigid, 99% cotton) stretches and softens with wear, allowing for a snug initial fit to become comfortable without significant waist gap, though for curvier figures, sizing up or trying your true size might be needed to accommodate hips and thighs, making trying multiple sizes the best bet.
