I was never that big of a fan of maxi skirts, especially living in Seattle where half the year is rainy and maxi skirts that drag around in the mud? No thanks. But I changed my mind when I was pregnant and pants were the last thing I wanted to wear. I found this size XL maxi skirt in the 75% off clearance racks for only $4, and the length was just right, but the waist was a little loose. It was the softest and most comfortable thing in the world and I decided that I'd alter it after having the baby because I had no idea what size I'd be by then, and just wore it as it was while pregnant.
Since it was too big, I had to hold it up with a Bella band, and one day as I got up from my desk at work to use the restroom for the 200th time, my butt felt surprisingly breezy. I quickly realized to my horror that the waistband had totally slipped down and my entire bottom was exposed. OMG. I looked around and thankfully no one saw... well, I think no one saw.
Needless to say, I altered it to fit better after that.
