Hello all I'm having a three piece/power suit custom made for me. As we were talking through the options I was asked if the back would match the front. I own many vests, but I've never had, or really noticed, the vest of a three piece suit with wool in the front and back. The vest will have a peaked lapel, 6 button, two pockets, no belt. It will be a dark navy suit with a red bead stripe that is faint and about an inch and a half apart. What are the thoughts/feelings on the back lining? Is a silk back less, or more formal? If I stick to wool, the thought of putting a different color wool in the back. Finally, what are your thoughts on whether the lapel should have the back portion of the collar or be a partial? Thank you for your input!
