Have no idea how I stumbled on to his thread but I am wondering when the hell did Perb Lounge turn into StyleForum's WAYWRN. I am sure Sperminator is a member there for sure.
To the OP - first go to the Forum I just mentioned for some education and answer to your question. Second, follow Sperminator's advice and style queue's he knows what he is doing that is clear.
Lastly, higher price does not always mean better. For example Armani (except his highest end line), Boss, Z-Zegna, D&G, Versace all make over priced suits relative to their quality. Stick with Canali, Corneliani, Belvest, Zegna (mainline, not Z) as a start (loads of others once you start looking). If you more coin to spend try Brioni, Kiton, Cuccinelli.
And more importantly than your suit imo, is the shoes. Learn the terms corrected grain (avoid like the plague), calf (good) and go with leather soles not rubber. Never, again Never buy anything by Kenneth Cole, Aldo, Cole Haan, Calvin Klein be it shoes, clothes hell anything.
