Wow! I didn't realize how expensive prom has become. Both of my DDs wanted me to make their prom dresses both years they went. I was happy to do it, and no one was the wiser. It wasn't exactly cheap...the trim for one of the dresses cost more than the fabric for the dress. But, still, nothing like what I'm seeing here.
Then when one of them got married, I made all the bridesmaid dress too since they wanted an arm and a leg and those girls, fresh out of college just didn't have that kind of money. I was able to combine two different patterns to get the look of the dress they liked from the boutique. I'm so thankful my mother taught me to sew when I was 7!
