I'm having a hell of a time finding bras that fit me properly, I'm usually sized at a 32 band size variable cup sizes. My issue is with the cups being too big or small. A 34C is too small. A 34D is a little too big. A 32D is too small.
Where do you buy your bras? Where do you get sized? What size do you think I am (more perspective 5'4" 130lbs)?
