Black Tie Appropriate?

Got this dress for an upcoming black tie wedding after deliberating on countless other dresses that just didn't speak to me. I've never been to a black tie event before and I worry this is too colorful or poofy. I have a backup but I love this dress so much. I just want to make sure it's appropriate.

Is this too white for a wedding?

really LOVE the fit and look of this dress but not sure if it's too light for a wedding. it's not white but a light tan colour

Formal enough for a semi-swanky venue? I'm shorter so it's about 2 inches above my ankle

Material is satin-y. My shoes will be a blocky heel that I wish were a bit fancier but I couldn't find anything comfortable and I'm broke.

I need your opinion wedding in August, golf course outdoor ceremony, indoor reception

Exact woding from invitation: "Dress Code Formal or Semi-Formal We encourage guests to wear suits & ties, midi or maxi cocktail dresses, dressy jumpsuits, or separates.

Smart-casual(?) dress code, how about this for my brother's wedding?

As much as I HATE wearing dresses, I have ordered this for my brother's wedding. I asked what the dress code was, and he said, "Smart-casual, I guess, any dress will be fine", UK wedding btw. I have ordered the Tira Pearl Mary Janes 'Sky Jewel Edition' - Blue shoes from KOI footwear, and I may wear some little, white, lace ankle socks with them. All the helpful advice on my last post has been VERY much appreciated. But now I need to know, what kind of thing do I wear on my arms? Like a jacket/capelet/shrug kind of thing? And, what colour? I have tattooed arms (from the elbows down) and fingers, and I don't need to cover them up. What do I search for? Thank you so much!!
