This bikini has a smooth front (no center seam) and 1" (25mm) sides. The front of the suit dips down a bit and is cut higher in the legs and rear. All of these features make this skimpy suit quite sexy and more revealing of your, um, personality. It is designed to be made without a lining (see sewing tips about swimwear lining).
