Re: Nursing bra with wide straps
Under bust is the measurement around your body right under your breasts against your rib cage.
Full bust is the measurement around the fullest part of your breasts.
Your band should fit snug against your body. Herroom.com has a great survey you can do to get an even better idea for your breast and body shape so you buy the right style of bra for you. It helped explain why even though I would buy the right size, the fit for me was often wrong. After the survey, I bought 4 bras that all fit really well. I learned which brand was the best fit for me in a select style, and will never have poorly fitted bras again!
