A nice idea, simple and quick to sew! The balloon skirt is simply connected to a long sleeve shirt.
Just cut your preferred lenght from the hipline to the hem. The width should be 1/3 wider than
the T-shirt width. Ruffle the skirt fabric to the width of the T-shirt and connect both pieces with a straight stitch.
The edges should be covered by zigzag or overlock. Pull a string through the hemline and ruffle there as much as you like… Bravo ~ finished!
And after the modelling, some snacks with the cool gang!
