Any help on fashion advice for a wedding?

One question- What time of the day is the event?

Also helpful if you know what style or color the bridal party is wearing.

I would always wear a dress and a big hat to a Wedding, or s facinator at the very least, but I am English and since having had a lot of Canadians attend my Wedding, I know that what is considered normal to wear to Weddings is different on this side of the pond...

one easy rule of thumb to follow is: if it's a fabric you'd wear to work, you can't wear it to a fancy wedding. this means no cotton, jersey, wool, tweed, etc. wear a dressy fabric like silk or satin (or something that looks like silk or satin).

unless it's explicitly specified as a black-tie wedding, i personally wouldn't show up in an evening gowns and jewels and an elaborate updo. you don't want to be overdressed. that being said, you don't want to be underdressed either. honestly, the best thing to do would be to ask your boss if it's a black-tie event. if so, follow what @kurenalkomo said. if not, it's a semi-formal event.

if this is the case (or you just reeeally don't want to ask your boss), you're trying to look very dressy but not too ostentatious. wear something elegant - no sequins, no bright colors (except red). accessorize with delicate, expensive (or expensive looking) jewelry. nothing should fall above your knees. a strapless dress is going to look nice and classy at a knee-length level; if you want the hem to hit the floor, make sure it has sleeves so it's not too showy. and, of course, you can't go wrong with a fancy LBD! (:

here are some examples of what i'm thinking:

hope this helped! have fun!

@HolyCabbage- I LOVE the 4th one (short black with side bow). That'd be great for a semi-formal, maybe even black tie with some accessorizing

This comes in a few different colors including this one and black, do you guys think this would work?



Sorry! Not sure how to make the imagine code work.

WOW! That dress is gorgeous! I can't see how that WOULDN'T work!

I wore this to my brother's wedding yesterday

It wasn't a fancy wedding, but dressy casual.
I got tons of compliments on it. I paired it with a little black cardigan and red wedge sandals.

It's an evening wedding. What sort of place is the venue? If she is getting married at 7pm in a garden, it'll probably be semi-formal. If she's getting married at 7pm in a church, it'll be semi-formal to formal.

The red dress is really nice and I think wearable for either semi-formal or formal depending on how you accessorize it. I wouldn't buy your choice in black, red, or any other color that pulls attention from the bride. Some more fashion-forward people won't mind you wearing black but some old school people (like the bride's grandma) might be offended if you wore black. My sister-in-law put out the word for the family to all wear black but that was the only wedding I have ever been to that female guests wore black.

I found a checklist on theknot.com that gives a general guide. It does say black is ok; YMMV.

I think you wear something simple but chic. Accessories would dress up any garment. Nice pair of shoes and the right amount of jewelry.
