What is the difference between a wireless bra and a bralette?

A bralette is a type of wireless bra. Wireless bras refer to any bra that is built without an underwire. Wireless bras can be extremely supportive, like a sports bra or full coverage molded foam cup wireless bra, or made with limited support.

A bralette is an example of a wireless bra that has little to no support. Bralettes are designed for maximum comfort and generally offer less coverage and compression than other wireless bras. Bralettes are ideal for smaller cup sizes and breasts that don't require much support.
