Indian outfit alteration recommendations

I’m very excited to be going to my first traditional Indian wedding soon and ordered my lehenga online from the site the bride requested. I thought I got the measurements right but it still needs a lot of adjustments. Is there anywhere in the San Antonio area that is experienced in this kind of alteration? It has some fancy stitching and hem-work so it needs to be hemmed from the waist. I also am not Indian so I want to make sure I don’t look like a fool— somebody steer me in the right direction please!
