As cool as Travis Touchdown looks in his default attire in No More Heroes 3, you might want to change his appearance at some point.
The good news is that you can; there are plenty of clothing options to unlock for Travis in No More Heroes 3, and then you can change in and out of them as you please.
To change your clothes in No More Heroes 3, simply pay a visit to the wardrobe in Travis’ room back at the motel in Santa Destroy. There, you can change into any outfits you’ve unlocked, as well as change your t-shirt. Use the shoulder buttons to switch between them.
You’ll unlock more clothing options as you play through No More Heroes 3. Many are awarded for winning ranking battles, for example. And as you explore the open world, keep an eye out for t-shirt icons. Talk to the aliens they represent, and they’ll offer you clothing for completing certain conditions.
Just be aware that your clothing has no affect on your abilities – it’s purely a cosmetic choice. So, either dress Travis up according to your style, or leave him in his default attire. It doesn’t really matter in the long run.
