This Gelmart bra used the M-frame design, similar to the popular Playtex 18-Hour bras. This model was discontinued a few years ago. This design gives good support for a wirefree bra with elastic panels on all sides, and the two section cups give good shaping. Most users find this style of bra to be very comfortable.
Originally a white bra, I dyed it a light purple using Rit dye and added a few pictures showing it after dying. I think it came out looking quite good, though the pictures aren’t the greatest.
