My DD is an F cup. She's almost 18. I've noticed her wearing her sports bras more than her normal bras. I can fully understand the comfort issue.
In the past I've spent out to buy her bras and wonder if I can get her something that is not a sports bra but has the same comfort. Is anyone making anything for an F cup?
If not a sports bra, then a bralette, or bra which is non-wired but structured in the right places - like the sloggi zero feel bras.
