How to Pick the Best Bra for Backless Dresses? With bras, just like it is with shoes, purses, and little black dresses, one design is never enough. And, after all, with so many varieties that each come with a particular purpose, why shouldn’t you shop for the best available option, right? You can use a t-shirt bra for a regular casual look. You have the plunging brassiere for dapper evenings and the lace lingerie for an outing that appeals to all your senses. But, when it comes to a halter neck, off shoulder tee, or a gown with a bareback, your savior is a strapless bra. A Backless Bra Is a Must-Have Item Be it a lovely halter neck ethnic wear, a sheer chic top, or a long, strapless, slim-fit, mermaid tiered skirt-dress, with a backless bra, you can wear any of these and not have to worry about a showing strap that can ruin your look.
