inbetween B/C ??? awesome

I'm inbetween a B and a C cup, but standardly a 36. I got the 36B and I LOVE it. I wear it for yoga, spin and mostly everyday use (haven't tried it for running yet, but I'm not afraid after reading others' reviews). It's nice because it looks good under work clothes (no back buldges) and I can zip outside for a walk at lunchtime and I don't have to change. I would love to see MC make a Fiona but with a little lower cleavage neck (just a little) so I could wear it with more everyday clothes and NOT see a bra at the top of a scoop neck or button down shirt.
