Considerations for clothing: Avoid multiple contact points (skin in constant but variable contact with fabric). Tight fitting clothing will itch everywhere if you perspire a lot. Tight collars, sleeves and waistbands can be as bad if not worse. For comfort: No tight sleeves, collars, waistbands. Wherever fabric tends to gather, bunch up or bind, those are places where morg spores (my own term) could be trapped. Wherever your sweat will accumulate without being immediately absorbed by fabric = danger zone. sweat + morg spore => rehydration of morg spore and a bite.
You'll notice when you get upset and you start to perspire, the bites will happen along your hairline and where your skin and clothing connect consistently (bra straps, etc). Almost like a prickling sensation.
Interestingly when I was reading up on static electricity, one of the old standby's -- baby (or talcum) powder was recommended as a good preventative.
In keeping with the electrostatic involvement--synthetic materials, (either because they do not contain DNA, or because they hold little electrostatic charge), seem to provide a kind of shield.
Recall: low levels of radiation can be blocked by something as light as paper. From a US government webpage on radiation:
"Alpha particles can travel only a few inches
in the air and lose their energy almost as soon as they collide with anything. They are easily shielded by a sheet of paper or the outer layer of a person's skin. Alpha particles are hazardous only when they are inhaled or swallowed.
Beta particles can travel in the air for a distance of a few feet. Beta particles can pass through a sheet of paper but can be stopped by a sheet of aluminum foil or glass. Beta particles can damage skin, but are most hazardous when swallowed or inhaled." source: http://www.epa.gov/radiation/rert/radfacts.html
"Radiation" is merely energy being emitted by a substance. So if the morg are attracted to electrostatic energy emitted by human victims, then effective shielding would be predicted to reduce reinfestation symptoms.
Some serious clothing options for experimenters: I don't have a bunch of money, so I haven't tried them, but I'm guessing UnderArmor is probably a good product line. It was originally designed for cops to wear under their body armor, hence the name. It's a very smooth, single layer design that is engineered not to gather or bunch up.
Its name also suggests that perhaps it has been manufactured with an eye to protecting cops against such things as could get beneath a vest and cause an officer irritation. (Hmm, no cops have come forward with morgellons...coffee and donuts might be an effective antidote : )

Meh. Who knew?
Other possibilities: GoreTex, which is a fiber that wicks moisture away from the body, releasing it outside of a densely-woven ("waterproof") plastic outer-layer.
Any tight-weave single-layer microfiber...like thermal ski underwear or cotton t-shirt material, or denim, can be equally effective in shielding, however effectiveness is compromised if moisture is permitted to accumulate.
Today, polyester and rayon are used to make garments with gathered sleeves, ruffles, collars etc. and the weave (known as "woven knits") increases the fiber's surface area, making woven knits potentially risky.
SHOES are a whole 'nother matter completely...
