Gradually shrink her clothes

You decide to try something new in your pursuit of nudity. As Shallan rummaged around her closet for a replacement for her discarded dress, her butt swayed invitingly. Reaching out with an invisible energy tendril, you connect yourself to her silken shift and shrink it slightly, resulting in an almost imperceptible tightening of the fabric around her bottom and breasts, the shift rose slightly, revealing a bit more of her lush thighs. Once again, you reach out and shrink the shift, making it incrementally tighter. Shallan continues to curse and search for a dress. Seriously, how long does it take? You decide to see if you can target specific parts of her clothes to shrink. You're curious to see what kind of panties she wears, and to get a closer look at that ass. The bottom section of the shift slowly began to cling closer and closer to her behind, revealing her boring black panties through the fabric. 'Aha! finally a clean havah!' Shallan exclaims, holding up a navy blue dress of the exact same style. Is that all this girl wears? Time to diversify her wardrobe. By dematerializing it. In a loud poof, the whole wardrobe and the havah she held in her hands disappeared entirely. This time, Shallan was utterly speechless with confusion, slowly backing away in shock. For good measure, you reach out with another tendril and shrink her shift once again. This time it becomes tight enough that she somewhat notices the filmy fabric clinging to her back more than usual, absentmindedly picking it away. This gradual shrinking of her shift wasnt being very effective, and your patience was running out. You needed something better, and faster.
