A dress that’s too long can be a tripping hazard—not exactly ideal for your walk down the aisle. Luckily, hemming is one of the quickest wedding alterations a seamstress can do. Most gowns can be shortened within a day or two, but certain fabrics—like lace or beaded designs—might take a little longer. The key? Try on your dress with the exact shoes you’ll be wearing to get the perfect length.
