I’m a 34C in Maidenform bra and I’m debating whether to get a size 6,8, or 10 in the Lululemon Energy Sports Bra- Medium Support B-D. My underbust (band) is 34 inches and overbust (chest) is 37 inches. Also if you have this exact item, what number size do you have in this sports bra and what is your bra size? Thank you for any help.
