First up is the best item out of all of them: Ryo's Jacket! Made for both men and women, Ryo's jacket is a near perfect replica of the one seen in Shenmue. Yeah, the diamond patch on the front is missing, but I can assure you that the tiger is on the back. Considering that blue jeans and white sneakers are default items, one could easily make a Ryo costume.
Up next is the stylish Amigo sombrero. I don't think Gagaman has a 360, but if he did I'm certain his avatar would have one of these.
AAUK of Sonic Wrecks went into detail on why Amigo's hat isn't larger:
A couple of other items bit the dust like Beat’s skates, I even had it down in my plan that your avatar action would become the little victory jig he does, but alas again the skates fell foul of the bounding box of the avatars, you can’t elevate the Avatar itself and neither can you have things going through the floor. You may notice the Amigo sombrero isn’t as wide as Amigo’s normally is, this is for the same reason.
Despite the restrictions, the hat looks great! I know what I'll be wearing on May 5th.
Finally we come to Beat's glasses. While not based on the original Dreamcast game (these come from JSRF) they still look quite cool and would go great with a yellow t-shirt and some headphones:
Overall the items are very cool. Prices for clothing and accessories range from $1 to $2, with props selling for $3. If you have extra points or are willing to spend a few bucks to dress a digital version of yourself, give it a go!
