Prices are not flat and may range anywhere from $6 - $25. At the very least the fabric of the garment, detail of work, and completion time are considered before a price is given. Frank and his staff will likely advise you come in for a fit and fair price quote.
The price will depend on the original garment quality and fabric. There are no 'flat rates'. The workmanship will be impeccable. I have had garments shortened, lengthened, relined, furs restyled. Over the years, no job they cannot do well.
