The Easy Elastic Fix
I instantly fell in love with the pattern of these shorts! It was a final sale item online, and typically I would never purchase something that I haven't tried on and couldn't return, but I just couldn't pass them up. Luckily, they were only a couple inches too big, so I was able to fix it with a piece of elastic I already had.
First I measured only the back side of my waist (not all the way around), subtracted 1 inch, and cut my elastic. Pin each end of the elastic on the inside to each side seam then pull the waistband straight so that the elastic is stretched all the way across, and sew the elastic down. This is easier to do with a sewing machine, but I sewed it by hand. You might have to get creative to stretch the elastic and sew at the same time. I held one end between my knees, stretched it with one hand and sewed with the other. You can also try hooking the waistband onto some heavy furniture, or asking a friend to hold it and chat with you as you sew.
