What is a Brazilian thong? Brazilian Thong Bikinis are bikinis that provide coverage between traditional bikinis and thong bikinis. This is why Brazilian thong bikinis make the perfect bikini-style option for women looking for the thong bikini, which is more discrete than traditional bikinis but with a bit more coverage than a classic thong. While they provide more coverage than conventional thongs, Brazilian thongs are generally considered one of the bikinis available in the market for women's swimwear. They're also often referred to as cheeky bikinis due to the in-between coverage they offer for your backside.
