Keep in mind that the cost of alterations has nothing to do with what you paid for the garment.  The factors that come into play are the type of garment, the fabric, the construction, and the details.  Don’t be surprised if the alterations cost nearly as much or more than the garment.  The best thing to do is contact us for a conversation about what you need done.  We may need to see the garment in person in order to give you an accurate quote.
