I've noticed my bras don't seem to cover far enough into the area between boob and armpit. I'd say I need a good inch of extra bra to cover it. My band is loose yet leaves marks so I'm not keen to have a tighter band. I've done to boos or bust measuring and nothing I've ordered has fit in the sizes they recommend. Currently wearing a 34d. A 32dd is far too tight in the same style. I've tried all sorts and nothing seems to fit comfortably. What am I doing wrong?
