Creative punishment for teen who spent irresponsibly on designer shoes?

This summer my 17yo daughter went backpacking through Europe with her older sister and we made a credit card she could use during the trip for normal expenses and any emergencies. Afterwards we decided to let her keep the card as she does rock climbing and sometimes travels with her hiking club to remote locations on weekends and we thought it would be safer to have the card with her when away.

But this morning when she was at school I went into her closet to clean as our cleaning lady was sick and found this pair of fancy looking 5½ inch heels which after looking through her credit card statement turned out to be actual Jimmy Choo’s which she bought online from Sacks Fifth Avenue for the low price of $750!!

So once she got home from school today I made her cut her credit card to little pieces herself, took the keys of the brand new VW Bettle we bought her on her birthday, took her cell phone away and had her stand in the heels on one foot with her nose on the wall in the living room for the rest of the day – allowed to change the foot she had to hold up every half hour.

Now I’ve sent her to bed but I need some creative ideas about how to punish her further for this absolutely irresponsible behaviour which will not be tolerated in my house. We already promised her that she’ll spend the entire saturday and sunday wearing the heels and on one foot with her nose on the wall but in the longer run i’m kind of running out of ideas what to do.

P.S.
Some ppl already replied saying standing on one foot in the heels is too much. I disagree. Maybe in the US it would be considered abuse or something but with all do respect, in that country schools now have metal detectors at the entrance to avoid kids bringing guns to school. We are from the US but live in Asia and here the mindset is a bit different. So I find standing on one foot uncomfortable no doubt but to make this something to remember and avoid in the future I need it to be uncomfortable otherwise it would not be a punishment would it?
