I bought a second-hand wedding dress and it fits almost perfectly, except that it's quite tight over my bum, causing the fabric to stretch and crease here. It was originally custom-made so I don't think there is any seam allowance for the dress to be let out - but there is a button and loop back closure with the buttons an inch or so away from the edge. Do you think it would be possible to either shift the buttons over the bum towards the edge, or replace the non-stretchy loops there with some more elastic ones?
Don't want to take it to a seamstress yet as I won't be needing it for a while and might change shape in the meantime! Would really appreciate any thoughts, I really do love the dress apart from that!
thank you
