Red satin 1940s cape dress from voodoo vixen

Really pretty, new with tags! This is a lovely fit and flare dress, no stretch, the cape ties at the back. I’m a large 10/small 12 and can zip it up, barely, but it’s tight and not comfy. If I slim down a bit before it sells I might keep it lol. My mannequin is slightly bigger than me at 35 / 30 / 38 and it fits her waist, but can’t quite zip up the back (see pictures). No stretch so do be sure it will fit you! I’m listing it as a 10 but I’d say it is closer to a Karen Millen size 10 than high street. Has a few loose threads that i can snip as pictured (how it was sold to me). It needs a good iron as it got folded in the post when I bought it.
