Yet another shirt and suit combination question again.

Are you in the wedding or just appearing? What is the climate and is it a wedding for some rich tycoon or one of your college friends? You don't want to dress so well that the bride ditches her fiance for you.

Apologize for nothing except that tie knot. 

 

That aside, this is a mess to me. Dark shirt + light tie is a big no go in my book. Are you wearing a suit jacket or a tux jacket? Either way it looks like you are wearing non matching trousers which is another no go. Also, I hate purple. If it were me I would avoid it at all costs, unless you are in the wedding party and are being required to dress this way. In any case, the shade of your shirt screams "Joker" IMO.

wow, um, not good.

1. That tie knot needs to never be worn again...period.
2. light tie of the same coloring as the shirt is immediate fail.
3. Tie clip is far too high
4. Doublebrested vest looks horrible in this situation. Just too many layers, which is very noticeable with this jacket. I'd lose the vest
5. Is this a single button jacket? Is it a dinner jacket? Are there matching pants?
6. Although tough from the angle, I'm guessing your sleeves are too long.

Here is what I'd do.

Step 1. Burn that shirt or put it in the "clubbing" category only. That is not formalwear.
Step 2. Put the vest back on the hanger and leave it there.
Step 3. Put on or purchase white or light blue dress shirt
Step 4. use the same tie, but depending on the shirt collar, tie either a four in hand (point collar) or windsor of reasonable size (spread collar)
Step 5. Tie clip lower, between 3rd and 4th button
Step 6. White linen pocket square


Assuming the stuff fits well, this will have you looking appropriate and stylish without looking like its your first time playing dress up.

good luck

Agree with much of what has been said. In general, avoid shirts and ties that are different shades of the same color. There are some combinations that look good (light pink shirt with burgundy tie, light blue shirt with dark navy or midnight blue tie with a charcoal suit), but be careful. Lilac shirt and dark purple tie is not one of those combinations.

1. The safest shirts are either white or light blue. I prefer light blue since most non-blue ties look better on it than white IMO. Avoid shirts that are dark in color. White, light blue, pink, lilac, and cream can work well as colors. Some dark patterns on a white background (e.g. stripes or checks can work too). Dark blue, red, purple, or black solid or semi-solid shirts are NOT dress shirts. Either wear them for a night out clubbing or in a casual situation. They should never be seen with a tie.

2. Do NOT wear a suit jacket without its matching pants. Ever. If you want to wear a jacket with non-matching pants, get an appropriate sport coat (e.g. a navy blazer).

Harsh, but relevant.
