Latest purchases and what to do with that tie

I have to admit, that until recently I did not own a single dress shirt with cuffs or any cufflinks. As I had one of those 150$ Groupon codes, I thought I’d give it a try and ordered a shirt & cufflinks from Indochino. Again, I changed a bit of the measurements on the shirt (more specifically, I added a bit in the shoulders and for the wrists). It turn out perfect, really. I like the fabric and the fit is great. Looks cool with those cufflinks too, waiting for a good opportunity to use them now… 

What is your opinion on tie bars, by the way? I have a style book that advices against them, but I’m not sure for what reason. The golden tie bar they sell at Indochino is perhaps a bit much, but a slim silver one…?

A main reason why I posted the pic above is actually the tie. I had ordered it already quite a while back from Dolbeau in Canada. The tie is really cool, but I just don’t have any idea what to wear it with! Can someone suggest a color or a specific pattern? It’s definitely more for play than for work.
