Liam Rokman - Calla inspired dress.
Nude net based, covered with an ecru guipure - handmade neckline and back, with additional pieces of the guipure attached by the hand to the top part of the dress: it makes the top less transparent than the normal giupure dress. Bottom is not see-through as there's a discreet sheer lining.
It's not strapless, but looks like it is due to the net (net comes from shoulder until cleavage, no risk of showing anything you shouldn't).
I'm 172cm and weigh 52kg, just for reference. You'd need to be equally slim, although the dress does stretch a little bit. Happy to book a fitting if you're in London or area.
