I absolutely love this Joseph dress. Beautifully cut and so, so pretty.
It would be a good fit for a UK10.
It is in good condition overall but please note that there are very tiny fabric pulls on both the front and back (think from where the sequins have rubbed against the silk when folded). Personally, I would still be more than happy to wear it - which is why I am happy to list the item on Manifesto Woman - but it might be a deal breaker for you. See final photo. I have marked down the price considerably to reflect these imperfections.
