Beetle is right. Throttle isn't.
The cause of this is that charm info gets lost on the way somewhere, so when the other player's client checks the requirements of your equipment, the stats from charms is missing.
If you don't meet the reqs without the charms for some of your items, the other player's client will think that those items are red due to too high reqs, and won't show them.
I think that's the correct explanation anyways. Could be wrong. I'm 100% positive that the charm stats are what makes you nude though.
[Edit] I guess one could call the selfsustaining str-boosting item thingie glitching too. That's not what causes nudity though.
