Yeah, my balance is terrible in anything other than the flattest shoes. I find that expensive styles can be imitated more affordably through shopping sales, thrift stores, yard sales.
Even though the video suggests tailoring, I think if you couldn't afford tailoring and didn't have the sewing skills to adjust things yourself, you could always use items that wouldn't need tailored such as a skirt, a blouse and a 3/4 sleeve or short sleeved cardigan as mentioned in the video.
