What was their reason for not letting you widen the lapels more? Their wide lapel havana(which has lot of the details you were looking for, IIRC.)already has a lapel wider than 4 inches, so it's not like they don't have suit like that.
Yeah, I like big drops better, as well. It's easier to prioritize what I'd like buy most, rather than never being sure if something else I might like more will drop later on. They just need to expand their MTO program and I'll never worry about this again.
