TF makes some of the most well made off the rack clothing available. It's on par with most bespoke. It's actually unlike most designer clothing in this respect. With bespoke, you wouldn't be getting such a jump in quality as you would a different look (every tailor cuts a different suit) and the ability to customize what you wanted about the suit. Since you like the TF look and don't know what you would want to customize, stick with TF. Me for instance, I dont like the TF look, so I'd go bespoke for those prices. But that's a personal decision. You do like the TF look, so stick with it.
