Wear speedo!

In reality, consider this.
Imagine you go in to get a new suit. It will most likely have to be altered.
Most of the high end clothing stores near me pharm out their work to local alterers, who take a week or so or more, especially if its during wedding/graduation season.

Imagine going into the same alterer with your pleated baggy cuffed 80-90's pants. They can pull them in. Easy peesy, but still the time lag.

I would find local alterer and get a timeline asap for getting something done. Take what you have in, and see what they can do. If they laugh at it, walk out, but that said- at least in my neck of the woods, the "high" end places, Brooks Bros. etc, will send you straight back to the same alterers. I'd go old school and make the vintage stuff fit, but that's just me. The new places are just gonna make you look like pee wee herman if you aren't careful.

Very high end clothiers will have their own fitters, but they are going to charge way more than a couple of bills- and you'll still have to check the lagtime.

You will probably find getting a more modern coat off the shelf a good solution for an initial fit, but a good set of wool pants will still need to be shortened.

Either way, the altering services are the important link here.
