DH and I are taking a self-defense class next weekend and he is insisting I get a sports bra. However I am breastfeeding and do not want one that is super tight as I will have to pump. I just bought a Bravada Body Silk Seamless Nursing bra that I think would work just fine but to appease him I am looking for a sports bra but don't want to shell out the money for a nursing sports bra as this will likely be the only time I wear it. Anyone have a suggestion for a decent/reasonably priced sports bra that works when breastfeeding?
