How to dress for a funeral?

Just wear anything nice that's black. You'll probably be best off wearing a suit.

Basically, you want to NOT stand-out, so being clean, tidy, smart pants, shirt & tie at a minimum (and polished shoes, very important). Suck it up and wear a suit though, a dark suit is fine it does not have to be black. No garish/colorful ties or socks, boring is the key here. You don't want to look like the day is about you and 'hey look at my lovely clothes', but you do want to demonstrate that you are showing maximum respect and effort.

This isn't about impressing your boss, he's not looking at you for that, it's about paying respect to the co-workers wife.

A navy, charcoal gray, or black suit with a matching shirt and tie. It doesn't matter who the funeral is for or how well you know the deceased (or the family). If you are going to a funeral, you show respect. Presumably you have lightweight suits in your wardrobe.

And hey, when my grandmother died a few year ago, it was June, the funeral was in Tampa, Florida, and it was almost 100 degrees. I still wore a black dress.

I'm not sure when people started dressing for funerals like they would to go dumpster diving.

There is only one acceptable attire for funerals.

The proper thing is to wear a suit, white shirt and dark tie.

It doesn't matter who the funeral is for.

Suit and tie would be nice, otherwise, a bit dressy. leave the flip flops (saw that), low rise jeans (showing your silk boxers..saw that), over sized jersey, Nike's, sloppy jeans (saw all that).....HOME. Turn your cell OFF. No surfer shorts (saw THAT). No jeans with the knees ripped out (SAW THAT...it's not really cool looking, only stupid. No t-shirts (with or without words/logo...saw that...LAKERS).

I was at the funeral of a fallen U.S. Marine a couple of years ago with my brother/sister Patriot Guard Riders and we saw all the above. Finally, a nicely dressed lady comes walking up in a black pants suit, low heels. HOWEVER....as she walked up the steps to the church, in large block chalk letters down the back of the right leg was the word SAMPLE. Plus, when the widow and her 2 children pulled up, those still outside ran up and acted like she was a movie star.....cameras clicking all over. I was DISGUSTED.

Use some decorum. You're an adult.

Dark suit and tie, dress shoes. Keep it simple. Etiquette is the same for Manhattan and Arizona in this matter.

Wear a suite in black.
