dont think you can transfer that
Not true, you can transfer any clothing from the first game. The only things you cannot transfer are:
Super Saiyan transformations
Kaioken
Unlocked Potential
Bardock's skills
Whis' skills
Any of those that you do happen to transfer just get changed into zeni/TP Medals. It's better to transfer stuff that will actually transfer, however, because you're getting zeni & TP medals based on what you did in the first game anyway.
