A racerback plus size bra is named after racing swimsuits that also have straps meeting in a “V” shape on the back between the shoulder blades. This bra style is an excellent solution for racerback tops and tanks. Having a racerback also prevents the shoulder straps from slipping off the shoulders. Racerback plus size bras offer better support to the plus size woman than traditional bras. Racerback plus size bras usually have a T-back design in the back, which provides bilateral support and improves posture appearance. Racerback plus size bras often feature a front closure, which makes them easy to put on and take off. A great racerback plus size bra is the Grenier Full Figure Cotton Underwire Bra 8467, which is made of 90% cotton and 10% spandex fabric.
