Nah man I wouldn't do it, It would look pretty gay in MY opinion. If you don't care about wasting the tape go for it though, you might have fun making it
i think it'd be legit. just get a normal tee and add length to it with the duct tape. and since you got different colors it be really legit. plus since its waterproof you'll never half snow sticking to the bottom of your tall tees anymore!
