Going to a wedding: Need help picking outfit!

A charcoal pinstripe suit and a checkered black & white shirt? I love the second tie but it would suggest a plain shirt (IMHO) I can't really imagine one of the ties to look good with that suit.

.

It seems there's far too much pattern going on with what you've posted. You can mix three or four different patterns, but it's incredibly hard to pull off.

Pinstriped suits almost always look best with a solid shirt. About the only kind of check that I like with them is a big windowpane in a soft color, which isn't too far from a solid anyway. With a solid shirt, the tie options open up quite a bit - either tie you posted would work well enough with a white shirt.

You're right, the gingham is in style right now, but I think that would look best with a solid suit, not pinstripe. So you gotta pick either or. Pinstripe suit with solid color shirt or solid suit with gingham shirt.

Pinstripes are fine - you are just going to be wise to adjust your thinking a little bit with the rest.

Go for a solid white, solid light blue, or a white shirt with a very faintly patterned pale blue houndstooth or check (VERY FAINT).

A solid navy or rep striped navy silk tie.
(Preferably not either of the ties you showed in your original post, the knit tie is too informal and the plaid tie is too informal AND will clash with the pinstripes. Although I do like that plaid tie and would snag it for other occasions. ) How wide are the lapels on that suit? They look about 2-1/2" wide to me so those super skinny 2" ties you are looking at will be a little weak with them - try to find something just a smidge wider - more in keeping with the lapel width.

The pocket square can then have some flair/color/pattern if you like, or can be plain white.

I know it's not what you wanted to hear - sorry. But I hope it helps.

By the way - what color shoes? You know black is the 'proper' color after dark right? This rule only applies to very formal weddings - so you can get away with dark brown or burgundy if you want.

Why do people come here and ask questions that they have already made a decision about?

If you think it looks ok, go for it. You may not be SF approved though. (or normal people approved, who knows)

Post a pic of said outfit for a definitive answer.

Dont wear a plaid or gingham shirt with pinstripes....PLEASE. Wear a solid blue or white shirt. A silk knit solid colored tie rarely looks good with a pin stripe suit. The tie is more casual and the pinstripes are much more business-like.

Wear the suit
a white linen pocket square
a white or blue solid shirt
a tie with a simple pattern but in an elegant color like purple or an interesting shade of blue with bits of white.

The effect should be similar to this

This is awful advice. Stop reading that magazine. Probably written by writer on a deadline who doesn't even own a suit.

Yeah, that guy's suit and shirt combo does not look good. They couldn't even find a shirt that fit him....his neck looks 2 sizes too big.
