Free People is our go-to retailer for billowy summer maxis, flirty bralettes and swimsuits, and a host of other trendy pieces. It has the whole sexy, going-out-dress market on lock, too. But, don't simply take our word for it: Rank & Style's unique fashion algorithm provides irrefutable evidence of the brand's popularity (among editors and consumers alike). The equation gives Free People's Tatiana Sexy Back Mini top honors as the best backless dress to shop for under $100. Rank & Style's statistic is culled from the product's 2,000-plus likes and glowing costumer reviews. The dress has a decidedly relaxed nature, — which is perfect for backyard BBQs, casual Fridays, and even as an alternative to beach cover-ups — but you can easily dress it up for date nights and fancier occasions, should the need arise. Did we mention it'll set your wallet back just $78 and it comes in five different colors? Go ahead and finish your outfit with lace-up shoes or casual, Birkenstock-inspired sandals and statement earrings. That's really all you'll need.
