This otherwise plain-looking set of clothing seems to have gossamer threads woven randomly into the fabric.

When you activate shiftweave, it changes your garb to resemble any of five specific outfits designated during its creation.
Shiftweave has no effect on any armor you wear (nor can it mimic armor) and does not change the effect of any magical clothing you wear.

Lore: Though originally created for wealthy socialites who wanted to avoid wearing the same gown to the gala, shiftweave is also useful to spies and assassins (Knowledge [nobility and royalty] DC 10).

Prerequisites: Craft Wondrous Item, disguise self.
Cost to Create: 250 gp, 20 XP, 1 day.
