Sisters Becca Taylor and Kristy Olsen founded Lilac Clothing to help moms-to-be love their changing bodies and look ultra-chic without sacrificing comfort. Made of cotton, rayon, viscose, and other soft fabrics, Lilac’s stylish collection of maternity clothes includes elegant wrap tops, printed sun dresses, and the best-selling Tummy Trimmer jean: a pair of soft, stretchy denim jeans that feature an elasticized waistline for a perfect, low-rise fit. Lilac’s curve-hugging Tummy Band, which doubles as a belly cover for nursing, comes in three different sizes and is a pregnancy must-have.
