I think the whole concept of "pulling off" is complete BS, whether that is for gens or reps.
In my opinion, "pulling off" shows insecurity and also the poor heuristics people use to associate expensive watches with class/background/attire/etc. I have seen people with minimum wage wearing gen daytonas, and I have seen multi-millionaires wearing my pompompurin factory datejust.
I think the better question to ask is whether you should wear a rep based on its fatal flaws / tell-sign that you can/ cannot accept. E.g., maybe one shouldn't wear a stock replica RM because there are still a whole load of tell-signs.
Ultimately, just wear what you want and enjoy.
