My suggestions: - 4 interior pockets. One on the right, 3 on the left. I find the lower pocket is good for tickets, but useless for mobile phones, as they often fall out when sitting. And for those times when I do put my keys in my jacket, I want them seperate to my phone. - The rubber shirt retainer strip in the pants are a fantastic detail. I love them. - Waistcoats. I don't know how it is in the rest of the world, but it's almost impossible to find a waistcoat for a reasonable price is Australia. - Real buttonhole on the lapel. That's probably a no brainer but thought I'd mention it anyway. I'd personally start with an un-cuffed, flat fronted pant, with a double vented 2 button notch lapel jacket . Once you have a base of buyers, I'd definitely move into options like cuffed, pleated and suspender button pants as well as external ticket pockets, and single button, peaked and shawl lapel low gorge dinner jackets. Perhaps even offer 3 button sb, double breasted, peaked lapel and single or no vented jackets too. I commend you on choosing to offer pants and jackets separately. I like having a second pair of pants for my suits, just in case the pants wear out.
