What is a sled?

And does it go with Morning Dress?

They're a pretentious term for a posh loafer, so no.

I was using it tongue in cheek. They’re vastly over worn and actually quite casual.

I'd look at the time and venue of the wedding and make my decision based on that.

and wearing black would be fine. Usually, it's not a desired color for a wedding.

It just means - when making a decision, go with the dressier option

What time is the ceremony? Reception?

Hee!

I think it is reasonable for hosts to ask guest to wear a certain style of clothing that is traditionally appropriate for an event ("Black tie"). I don't think it's OK to require guests to dress according to some My Special Day vision they have about everyone wearing a particular color. I think it's goofy to provide suggestions that aren't an actual dress code as though your loved ones don't know how to dress themselves, which is what "Black tie preferred" seems to be.

Wear a dark suit or dinner jacket if you're a suit-wearer. Wear a nice dress -- something too festive/formal to wear court, if you need a guideline -- if you prefer dresses.

Oh yeah, and wear cap toe black shoes that are freshly shined. No brown shoes, no broguing, no monk straps, or Gucci sleds.

Define “day time”? Is the event expected to conclude after 6 or 7 pm?

No one wears morning dress anymore in the US except super duper posers. That’s absurd and the response above is cringy and trying too hard.

The rules have slipped quite a bit in the US - black tie can include dark suit with white shirt and conservative tie or tux and as long as the event concludes around dusk or after, it’s pretty normal.

Semi-formal wear looks and feels ridiculous at 3 or 4pm, but unless you’re going to go change between service and reception (which is an option!), you’ll feel under dressed at a semi-formal evening reception.

If the entire thing concludes before dusk (especially if it concludes significantly before dusk or begins before 2 or 3 in the afternoon), I’d wear a seasonally/climate appropriate suit and conservative tie and white shirt. You could easily get away with a dark, light weight suit. Just make sure it’s well tailored and a muted (if any) pattern.

Asking someone to wear a full tux at 1pm in Georgia in July, for example, is grounds for immediate imprisonment. But if it’s Manhattan, you’re inside the whole time, and the event concludes at 5 in November… wear a tux.

You should write to whoever is hosting the event:

"I'm sure you didn't mean to suggest evening attire for a daytime wedding. Perhaps you intended to say 'Morning Dress'?"

What I like. If I have something uber formal I’d like to wear, I’d wear that. If not I’d just wear a nice cocktail dress.

I've been to many black-tie optional weddings, but preferred? Yikes. This is for a daytime wedding. What would you wear??
