BNWT although the silk is crumpled from storage and could do with being steamed.  US4 = UK 8. One shoulder. Back zip (double zip - of outer and inner bodice, in fact) with stiff but not boned bodice, so you would not need to wear a bra. Please see photos.

Please note I post as soon as I can but I am frequently away for work during the week so can only guarantee the first Saturday after your payment.  If you require earlier dispatch please contact me before you buy and I will tell you what is possible that week.
I do not post overseas so any non-UK deliveries are handled by eBay's Global delivery programme - the postage costs for this are set by and paid to eBay, not me, so it is a waste of your time and mine to request lower postage rates.
