NEW WITH TAGS ARQ bras. Only tried on. Bought em final sale and they didn't work for me -- my loss is your gain! ARQ is closing and these sizes & colors are gone! I would consider a trade for a NWT ARQ tank size S or a Magda bra in a size S :) Measurements: Band Size 26.75 inches* Fits Cup Size A-D *Band measurement taken unhooked. ARQ's sizing says this fits a rib size of 28-31", but I'm ~ 30.5" and it felt big so you could size up a little.
