Let us be the first to tell you this: Amazon is the mecca for affordable swimwear. Not only do most options dip under $100, but they come in eye-catching prints, colors, and new styles. So, we did what we do best and researched 15 of the best bikinis and one-pieces to shop right now. They’re all offered under the Amazon Prime deal, which means you can receive your new swimsuit in less than three days (an ideal option for your last-minute Memorial Day plans). You probably weren’t expecting it, but your new Summer bikini will come straight from Amazon.
