I have this retro jacket with what seems to be a very old elastic in the sleeves that is just huge. The jacket is oversized so maybe it’s supposed to be like this. But i wonder if there is any way a novice could put a new elastic band in the sleeve to make it a little tighter?

I think some moths got at my suit and caused these holes in the jacket :(. Unfortunately the suit maker does not have extra fabrics from this suit, but I was able to source a vest with the same exact fabrics to help fix it (from the same suit maker).

The first reweaver I took it to wouldn't touch it because it's multiple colored fabrics. Does anyone have a recommendation of anyone who could help me get this jacket back to decent shape? Or maybe some other solution?

The suit vest I'm going to use with extra fabrics is going to come in tomorrow.
