Buying other clothes is fairly easy, though most of those for sale are either typically tacky cf:"I <Heart> Kirruxir", overtly politicised "No animals were harmed in the making of this sweatshirt" (slogan imprinted both in Galanglic and the K'kree script) or both along with something masquerading as wit (bib with "Licensed Cooking Inspector").
However it's not too hard to find something more or less anonymous and discreet without being stupidly expensive. K'kree cloth is one of the few things they do very, very well and commands prices accordingly. What Gwydion can afford comes along the lines of bottom line cashmere - though as you might expect it's not an animal product.
OOC:
The ride is more of a slide walk affair, you queue up and go into the equivalent of an overcrowded cattle truck. Once that is uncomfortably full the back doors open and the main part of the ride begins. A key part of the design is that you do not so much walk through, as get moved through at whatever pace the designers like.
There are a fair number of one-way doors in the design, so you can only go foward, never back. Several warning signs also indicate that there are no exits, once you are in you stay until the end.* They also state that this is not for the faint-hearted and that "riders" sign a release before going in.
Needless to say this hype appears to collect a certain clientele, though the queue is not at all long.
* This doesn't mean that you couldn't sneak out, just that you wouldn't be using a designed exit and would be going in an "Employees only" area
