I imagine a really tight shirt, kind of like the one dudes were on Jersey Shore, in tie-dye blue with white splotches coming up from under the shirt; with a big red handie on the front.
And it's also short, doesn't even come over the waist.
And it also has Hugo "17" Boss on the back, kind of like this:
HUGO
17
BOSS
With some weird winged angel design or some shit.
