You don't have to be very far along in a pregnancy before your pre-maternity waist disappears. In the first and second trimesters I like to pretend that I still have a waist by wearing a belt above my belly. By the time the third trimester hits your rib cage has expanded , and the space between your belly and bust is practically non existent. It makes it rather uncomfortable to wear a belt, at least a traditional belt.
I was recently playing around with some of the stretch lace that I purchased for my maternity bands. I found that I could cut one long strip, stitch the ends together, and create a rather comfortable maternity "belt". It could easily be dressed up with a ribbon or brooch of some sort, and I also think that it would be fun to layer a normal belt over the top of the lace layer (once my abdomen isn't being inhabited by a growing babe).
Anyway, it's just a silly little project that I thought I'd share. Have a great weekend!
