I have a question. What is the difference between buying a slim fit suit or just buying a smaller size regular fit suit. Wouldn't it be the same thing?
Question about Slim Fit vs Regular Fit Suit
You're giving the tags too much thought. They don't mean shit. One maker's slim fit is another maker's roomy fit. To say nothing of how variable chest sizes are.
^Exactly... some makers only make a slim fit, so that is their regular fit.
Now I think I know what kind of suits the OP is talking about, and the difference is all in the cut, around the waist and shoulders, as well as small differences in lapels, sleeve length and jacket length.
It all depends on who you are buying from in the end
you should really be getting one tailored to your body shape as many have expressed on this thread a man may be of the slim & slender build but have the same arm length of the gentleman buying the regular fit. So to answer your question precisely no.. they are not the same thing.
