Shiftweave

From Eberron: Rising From the Last War, page 277 and; Wayfinder's Guide to Eberron, page 115.

Description
Wondrous item, common.

When a suit of shiftweave is created, up to five different outfits can be embedded into the cloth. While wearing the clothing, you can speak its command word as a bonus action to transform your outfit into your choice of one of the other designs contained within it. Regardless of its appearance, the outfit can't be anything but clothing. Although it can duplicate the look of other magical clothing, it doesn't gain their magical properties.
