Dress of Many Pockets (Patreon)

Wondrous item, common

This dress has six pockets that can be magically shown or hidden. While wearing the dress, you can use a bonus action to cause any number of its pockets to appear or vanish from it. The pockets can be located anywhere on the dress, and needn't be in the same place each time they appear. Each pocket is large enough for a small parcel, measuring no more than 4 inches in any dimension and weighing no more than 2 pounds. While a pocket is hidden, its contents are magically moved to the inside of the dress and evenly distributed throughout it so as to not affect its delicate appearance.

"I like your dress."
"Thanks! It has pockets!"
