So yeah, I want to make a shirt like that, but I would like to have it longer (to my waist) and preferably have the main body one peice. Actually, if it was possible, the whole thing from one peice.
If it's not possible thats cool, too- but I really suck at sleeves.
What shape should the sleeves be?
How do I attach them successfully?
Gah I feel like this should be such a simple question that I just can't get!!
