Both sides can pop off to nurse. Racerback style clasp on the back. Removable padding. Can be worn to exercise in or as everyday lounge. This bra has had very little wear and it’s never been in the dryer. I love the fabric and I think this bra has a great style unfortunately it’s just too big for me even as I’m breastfeeding. I’m normally a large in Alo or a 10 at Lululemon and this bra is a little too big in me otherwise it’s a great bra! Smoke and pet free home.
