With very rare exceptions (namely white square with a somewhat formal dark outfit), I can't stand showing points, or any intricate folding for that matter.
I always do a simple folded puff. Easy enough for me and I like the way is softens the look.
gdl - are all of your squares silk or do you have linen as well? I like the way they look.
Well, I think it's key to "lock down" at least one element. For me, and it seems for many, this is the shirt. Each of my shirts is wearable with pretty much any jacket or suit I can throw at it.
I do the same with odd trousers. Light grey is infinitely matchable, as long as the cloth is season appropriate.
This is a flannel, but otherwise I don't know what to call it:
I don't know what to call this weave, but it is in a weird, vaguely purplish colour:
The rest of my trousers are plain (flannel, twill or worsted) charcoal, grey, british tan or wheat. Because they are simple, I find them easier to use as an anchor than shirts, where there is rather more variety.
Thanks for the comments guys - I figured #1 was kind of outside the bounds of this thread, but i thought I'd throw it in there anyway. On #3, you can't see it that great in the pic, there's a little bit of pink in those lighter circles of the tie, and the tie is enough of a mid-blue as opposed to a darker navy that I think it's springy enough to not be too business for a linen blend suit.
