Try as you might, chances are there will be at least one weekend this summer that will require wearing a bathing suit. It may seem as though every store is filled with skimpy bikinis or frumpy one-pieces, but fear not! The fifties are back, and the trend is reflected in retro-silhouetted swimwear, with designers creating high-waisted bikinis or thigh-skimming maillots that will universally flatter figures.
