I've decided to wear this double breasted suit, but still not sure what tie. While this tie has a blue background, I think it may be suitable against the darker navy due to the contrast in shades plus the other colours.

Please ignore the OCBD (I'm getting a white spread collar shirt soon) and tile work in the background.

Other candidates include charcoal solid repp silk, black solid repp silk, black silk knit, dark red grenadine-ish (politician?). I'll get pictures if requested. Most of my repp-stripe ones are too close in base colour or comically narrow compared to the wider lapels.
Suggestions and constructive criticism more than welcome.
