Spandex style unicycling shorts that have an integrated suspensory to hold the dangly bits up and out of the way.
Jeans.
Tshirt.
Belt.
Shoelaces.
Why anything else?
Ohh man the summers here will fry you like…cheese gone bad. Meaning you wouldn’t be able to wear it. Either that or you’ll be burning hot. 
Ooh, I don’t know. I kinda prefer wearing my shoelaces with shoes tied to them.
Also, I like hats.
Basically I just wear some Orchid BMX shoes, long socks or my shinguards tend to rub off some skin… some BBB freeride shorts, they will NEVER wear down, very good shorts. A loose T-shirt, Municycle.com in this case, it being winter I tend to wear some sweaters, I’ve made my own sweaters called the EenWiel.nl Winter Sweaters 2007, unlike my other sweaters these don’t sweat as much, they’re very comfortable and don’t get too hot when riding. Some gloves and a helmet, though that’s not clothing is it?
If you’re looking for protection about your hips and arse you might look into the 661 bombershorts, I saw them on the 661 page once and thought they might be good.
I bought a pair of these, also thinking they might be good. However, they’re probably the most uncomfortable shorts I’ve ever worn. The big reinforced plates just don’t bend in the places you need them to, and they end up pinching where you don’t want them to.
They may be good if you are the kind of person that keeps throwing your hips at the floor, but if you’re not, then I’d avoid them.

I think GKMAC basically has it down per Muni riding. The idea here is to stay comfortable (minimal chaffing) on longish rides and to use functional, low-matainance clothes. After fiddling with various combos over the last 3 years I’ve found the following to be best for me, riding in Southern California.
Shoes: whatever you prefer.
Socks: Black sports socks (high nylon to cotton ratio), higher than usual to protect the shins from the ankle braces. Any color but black and the socks are ruined (grimy) after one ride.
Ankle braces: Strap type–have saved us many times from broken bones.
Shorts: First layer, some good quality bike shorts.
Over shorts: Loose, good quality, nylon board shorts, like Quiksilver, O’Neill, Rusty, et al. Pricy at 50 bucks but the cheap ones wear out in no time. Adds a little style to the fandango.
Shirt: Polypro all the way (cotton is the worst–can’t wick sweat and never dries out during the ride). We use chaep soccer shirts, the thin ones. The thicker ones are better quality but are normally too hot for So Cal. Layer on more polypro as needed. In cold conditions use a pile (polypro) vest and wear a nylon or polypro beany under your helmet.

Oakley Ballistic 2.6 shorts. That’s what I use and they’re fabulous (they run big - and expensive). Try to find them on sale somewhere, that’s what I did (www.steepandcheap.com). I wear a smartwool top when it’s cold (or underarmour coldgear), and just an adidas soccer jersey when it’s warmer out.
Cheers.
A high-riding crotch would also help. Then the shorts wouldn’t be pushed up so much by the seat.
yeah, a higher crotch will make for less "creeping, but higher crotch= less comfortable.
I’ve been wearing ZOIC MTB shorts for years and I really like them. The ones I have are designed with an integrated padded Lycra bike style short inside, and a cotton cargo short outside. The pockets are large enough for tools and energy food. Also check out their knicks…And for shirts Target sells C9 Champion clothing I have a DuoDry shirt that I like because it wicks away moisture and stays dry, at $10 its a better deal than a $45 bike jersey. I go for basic black…
I’d like some shoes that have a nice grippy bottom, but some sort of super-stiff insole for better power transmission to the pedals. I wonder if an insole can be made that’s stiff for pedaling, but flexes for walking?
My biggest complaint with most of my MTB shorts is lack of pockets. I like having a back pocket, and room enough for my crap in the front pockets.
Try using one of those adidas or nike strap bags (i dont know what they are called) that you just pull on the straps to close them, i keep my phone, wallet, mp3 player and keys in there, just make sure that you dont wear it when you are liable to fall on your back.
here, found them http://www.jcpenney.com/jcp/Products.aspx?DeptID=0&CatID=028709&Grptyp=PRD&ItemId=0fbde35&siteID=210054369
you can find them for like 5 bucks at walmart or target
Besides yoggi, do we have any actual nudist unicyclers?
i would google it but i fear google images may have quite an insight into the human body if i do so.
I actually like a higher crotch. I always buy jeans that aren’t saggy-crotched. You have to pay a good bit more it seems like, and you can’t find 'em at Fred Meyer or Walmart, but I love the feel.
I also have a feeling my above comment will get sig’d. 
felt like obliging you
just look down
You seem to be like amazing!!! Can you read my mind and then more 
Dr. Scholl’s makes a couple of insoles that have stiff plastic under the arch. They stiffen the shoe up right under the pedal. I use them in my 661’s which I find the sole to be too soft otherwise.

um balck under armour with no sleeves black pants and i would have my unicycle discuised as a pony and ride up with a sword
Pants:
Emerica had pants called “Lowrider”, a bit like these but with more stretch.
The stretch was ideal. And it had a nice flat crotch.
They suited like if they were taylor made. Unfortunely I found only 1 pair.
Shoe’s:
I haven’t tried the Emerica “Leo”.
I currently use the Duff’s Gambler (I have them in 4 colors).
Just like Dustin I tried Orchids, which are special made for BMX.
