This halter top is the perfect transition top. It’s from J. Crew! It runs generously but if you need length size up. I’m in the large but a medium would fit me as well. Side zipper so once you get your neck tied the way you want, it’s an easy on and off!
I’ve linked similar shorts bc mine are on sale but almost sold out! I’m in the 10 — true to size!
PS; I’m wearing a strapless bra.
