There is too much ruching around the hips - particularly at the back. That will accentuate width and make you look shorter. I also think the back looks like it has been cut by someone who doesnt know anything about pattern cutting - like the fabric has been forced to fit the shape.
This navy gown would look stunning with a diamante necklace and a cocktail ring (I wouldn't wear bracelets with this fabric....from bitter experience they are likely to snag if they have "claw" settings on them). You could further glam up with a faux fur stole or capelet. A beaded evening jacket/capelet would work just as well too and fits with the era.
Have you seen a Ghost dress irl mrshels if not do try to because the fabric is very thin and they are unlined. I tried one on and it was not flattering on the bum or tum at all (am size 12 5ft8 curvy) it was also a bit long on me so I think you'll need to get it taken up a bit.
If you do get a Clarissa i'd go for navy as a potentially more flattering non see thru option.
Hope i'm wrong and it wasn't Clarissa I tried so I don't know for sure but I thought i'd mention so you can try and see one for real before spending.
Thanks for the warning. I think I might order from the ghost store so I can return it if it's not what I'm looking for (if I decide to go with a ghost dress that is!) Am resigned to having to take it up miles, that's the story of my life. Will also be spanxed up to my eyebrows!
I agree that some of the Ghost dresses can be a little see-through. Depends whether they are crepe or satin. IMO the satin versions are far more flattering. I wore anti-VPL pants (can't remember which brand but from John Lewis) and they worked brilliantly. I'm not a fan of Spanx type underwear - can't bear the squeezing & increased temperature!
Personally I would opt for the navy Clarissa. It's got a lovely dramatic vintage feel to it - just what you wanted
