A Loosey-Goosey Brand Guide for Thrifting Suits and Sportcoats
I’ve had many requests for a list of brands to look for when thrifting.  Of course, this is a monumentally huge request, given the sheer volume of brands of all types of clothes that’s out there.  I don’t really think it’s something I’m even capable of doing.
Luckily, though, folks on various clothing fora have put together hierarchical lists of ready-to-wear suit and sportcoat brands.  These tend to be based on things like amount of hand work, canvassing, fabrics and so on.  These aren’t the end-all, be-all of quality - if you’re Rod Blagojevic, then you want Oxxford to look like a competent guy who won’t get all graft-y, and if you’re an Italian playboy, you might want Kiton or Isaia to look like the kind of guy whose yacht travels with its own cigar boat.  Different brands have different meanings, fits, and values. 
That said, these brands, grouped into two loose agglomerations (super-mega excellent and very excellent) produce high-quality goods that are worth looking out for.  I’ve left out mid-tier brands (like, say, Brooks Brothers main line) because things get a lot murkier around that level of quality.  There are plenty of clothes worth wearing at that level, and you should not be ashamed to buy and wear them, but the brands listed below are consistently superb.
Again: this list is mostly alphabetical, and somewhat to very arbitrary.  It’s mostly a tool for folks who want a reference to help them identify the best of the best when bargain hunting.  I’m sure I missed stuff, and the ranking system is loosey-goosey at best.  Nonetheless, I think it will be of use.
