3 and 4 are also good. 2 as well probably (though I don't wear navy neats since Inrately wear gray suits). Colorwise, I dislike the idea of a tie "popping." I like subtle. And the yellow and lavender just aren't that. Anyway, what sets those apart is going to be color rather than pattern or material.
The lavender is better than the yellow, which I don't think looks good, generally, against white OR blue, though for different reasons.
An aside: before I read that it was what I had recommended, I thought to myself, "oh, six is nice." So at least I'm consistent!
Haha good to know you are consistent I ended up buying all those ties you recommended. I love the color and pattern on the ones that have arrived so far. The quality difference is very noticeable (the tie above is J Press I think) - the Kiton and Marinella ties are some of the nicest feeling silk I own while the J Press is far more standard.
