I found another way to make a tube dress.
It is a little more time consuming than using the elastic, but it looks a lot better!
I lost the link, but it is a video from "threadbanger". Something along the lines of "spring dress" or something! I'm so sorry I can not find it! I will link you guys when I find it, or someone else has found it!
But please to check threadbanger videos, they're full of all kinds of sewing videos you've ever wanted to learn!
Just search them up on Youtube or you can go to their link:
