Completely agree. When I first started on SF four years ago my best suits was a Hugo Boss. Now my "low end" suits are HSM. I.was able to do this with the knowledge I gained here both thrifting and to realize what is too good to pass up retail.
Unless they don't fit you keep them.
HSM makes a nice $1,000-ish suit, but I haven't seen a wearable (recent) $3K suit on this thread in months. You can thrift a $1,000 suit for $10, but a $3K suit is going to run you $500-$1,000. (Thirty-year-old Oxxford stuff with 4" lapels excepted.) And you're going to have to hit the consignment store the day after the opiate-addicted son of the local Italian senator drops off his dad's stuff.
