After losing weight, it is common for clothing to fit loosely. You have a choice to either purchase new clothing or alter the old ones that you have. It would be more cost effective to do alteration, instead of spending money on brand new clothes. Before you start altering your clothes, there are certain things that you should have handy. With the right tools and technique, you can alter clothes after weight loss on your own, without having to pay a seamstress to do the job.
Things You'll Need
Needle and thread
Examine the clothing before you decide to alter it. Lay the clothing on a flat surface, then place a piece of clothing that fits you on top of it as a guide. Mark the new stitching line where you will be making the new seams, using tailor's chalk.

Fold the new seam and crease it with your fingers. Baste (sew loosely) the seam with a needle and thread. Carefully try on the clothing to make sure that it fits correctly. Make adjustments as needed.
Sew the new seam that you created with a sewing machine. Trim off the excess material from each side of the seam using a pair of scissors. Iron the new seams to keep them flat.
Ask a friend to mark the areas to be altered while you are wearing the dress. This is another way to get an accurate fit.
