Yayy, you just gave me the want (there is a better word for that but im too lazy to think about it) to make this! i had an old t-shirt that is super large and is long...and i wanted it to be off the shoulder one. well now its done.
I always do this to my tshirts, it makes them look really good. What looks quite cool is wearing a tight fitting long-sleeved top underneath in a contrasting colour, and tucking the shirt loosely into your trousers =)
Love this though, I may have to try it.
Thanks for the great project!
