Basic reversible bikini WELL'S BAY sewing pattern by Halfmoon Atelier is a strikingly simple yet functional bikini. Named after the "disappearing beach" in honor of one of the most breathtaking spots on the island of Saba.

This bikini is originally created to use the stretch of strips of swimwear fabric, which refers to as being "elast-ish", rather than special elastics or other notions (although elastic is optional). The wireless top has ties in the back, thin shoulder straps, and underbust darts. Due to the curved seam of the side panels, the bottoms are low-rise hipsters and offer complete coverage. The reversibility gives you four different wearable combinations and plenty of opportunity for color-blocking, making it perfect for the minimalist who can't decide. (The pattern comes with bonus tips on creating panties with the bikini bottoms pattern!)
