From Cashmerette Patterns:
Soak up the sun in the Ipswich Swimsuit! This modern pattern has two cleverly color-blocked variations: a one-piece swimsuit with a contrast waistband or a high-waisted bikini with piping detail. Both suits feature supportive straps, and an optional underwired foam swim bra and boning, so that you're comfortable lounging by the pool or playing volleyball on your favorite beach. Mix prints and colors for a swimsuit that celebrates your body and your creativity.
