Of course you have to have considerable input. The concept that's being expressed is that much of the window-dressing is feminine, and most fellows just say "Sure, Babe. Whatever you want on that!"

For my own wedding, I made my own decision on my tux... and discussed it with my wife. I also asked her not to put her hair "up" as was the fashion of the day, because I so love it down, and she did that for me. I did much for her too, but the choice of bows and candles to decorate the church? Give me a break. That's just not "guy stuff" to me anyway.
