I made my oldest a twirly skirt out of some knit I got at Hobby Lobby a few months ago- she really wanted to have a Strawberry Shortcake outfit and hey, the knit was perfect with the pink and little green dots.
Unfortunately, it was really cheap knit.
After pre-washing the fabric (I knew it would shrink; it was cotton, after all) I cut it out and sewed in the waistband. After the first wash after it was worn, there was some serious wonkage going on, so I re-cut the skirt part. It made it a little shorter, but I had made it long to begin with so it wasn’t a big deal.
10 washes later, it looks like this again. The waistband is now 2” too wide, too, so even though it is shorter, it sags a lot and I usually end up tucking the skirt into her underpants to get it to stay on.
After this last wash and her wearing it this morning… it was time to just toss it. Cheap knit = wonky skirt. It is just the way it is. Too bad, because I was hoping this would last until October and Halloween’s Strawberry Shortcake costume.
Moral of the story: Buy nicer knits.
