Corset of Holding (3.5e Equipment)
From D&D Wiki
|Aura:||Moderate; (DC 18) conjuration|
These overbust corsets are typically made from leather or brocade and have mithril boning. These items automatically size themselves to the wearer in the most flattering way possible and self-lace (and unlace) on command (only by the wearer). The wearers bust is generally displayed to great advantage, granting the wearer a +2 circumstance bonus to charisma based checks. Additionally the bust portion of the corset acts as a bag of holding that weighs nothing, holds up to 250lbs of equipment with a max of 30 cubic feet, and the wearer may put items into and take them out of the top without disturbing or damaging their breasts.
