I found a suede leather skirt by Vince in a consignment shop. It is 1 or 2 sizes too big on me in the waist. The length is fine if it sits on my waist but the skirt falls to my hip bone at the moment. The skirt is lined. It is a wrap-style skirt but I don't remember seeing a buckle. Maybe there is one (I can go check tomorrow if necessary).

I don't have much experience with getting clothes altered. Is it possible to alter a leather skirt? What are the factors that change the complexity/risk of the alteration?

Edit for clarification: I am not altering this myself. I am pretty terrible at sewing
