Okay, there’s nothing overtly Hawaiian about this bikini. You may as well call it Gidget Goes Californian or Gidget Gone Wild—that is, if Gidget likes to get wasted and flash her tits (the buckled front makes it tempting!). But with wide criss­-­cross straps, a fetching front­-­buckle closure, wedgie­-­proof lines, and a darling little belt, this stretchy bikini is as Gidget as can be. Form follows function, so the bra band is doubled for extra support and beachside security (use the doubled band as a casing for roll­-­proof 11/4”/3cm elastic for even greater support). Stretchy Katrina yarn has built­-­in memory, and the garter stitch texture forgives a not­-­so­-­teenage ­ass.
