Floral 70s/80s halter maxi dress

Floral halter maxi dress. I believe it may be vintage or handmade. Cups are safety pinned in, can be removed. It is shown on my size 4 mannequin and it fits very very tight. I would recommend for a size 0 or 2. There is no size or brand tag. Back zips up. Very 70s/80s vibes. No flaws. From a smoke free, pet friendly home
