Wedding Dress Alterations. What do you do when Pre-Owned Wedding Dress won’t zip up? I fixed it. There’s a lot that goes on inside a Wedding Dress during the Bodice alterations. When altering the Bodice of a Wedding Gown, you often have to get up in between layers to get to seams that need to be taken in/let out. This is not for the faint of heart… you have to know the consequences of each stitch…This dress had 9 layers and a long train with a lot of lace. Here I am sewing on lace appliques. Don’t you love it when BEAUTIFUL comes together!!!
