The red tie is to be worn with the white shirt and the white tie will be worn with the blue shirt. I'm no good at matching clothes so the sales lady picked out the 2 shirts and 2 ties for me.
For my opinion you need wear that color suit what you like. It doesn't matter what people think. For example on my wedding i was in green-blue suit. Something same with this gamma create.vista.com/colors/color-names/light-sea-green/ And that was awesome
