When I started playing there were only a couple of outfits available, Wild west and ceremonial kimono, now there are 8 that you can obtain in events and one that you can obtain in regular shop. 8 is a large number, and the time traveler one will join soon. Wouldn't it be better if at least two of the older outfits are added to the regular shops? I'd suggest "Ceremonial kimono" and "Summer youth sai", since they're the oldest ones and everyone in older servers that play regularly should have them already. That would help people in older servers get the outfits they want, and people from newer servers to catch up faster, since there's so much to obtain.

As for the price, I think 75 coupons a fragment like Wild west is fair enough.
