Something you can use day and night.
I love jumpers so when I got a xxl T-shirt in a assemby at my school I said why not turn it in to something prettier? This is my first project so I hope you like it as much as I do.
Try your t-shirt on and mark where you want the sleeve to go.
I prefer my left shoulder but that is optional(do the opposite of the shoulder you want, remember the t-shirt is inside out). Pin the sides so the t shirt hugs your body as you like. Leave about 1/4 of a inch in each side when you cut.
Cut and sew. When you sew the side of the T-shirt without the sleeve stop at the waist. So that from the waist up is left without sewing.
and you are finish! now you can add something to make it more your style I just added a belt but you can do anything you want with it. enjoy!!
