I am a very casual dresser day-to-day, but I am the plus one to my husband's first holiday staff party in a neighbouring major city. The theme is Las Vegas (??) and we weren't provided any further information or dress code beyond that. I took the theme to mean cocktail attire and want to make a good impression, but anything in the cocktail attire world is out of my normal comfort zone so I'm feeling quite lost on how to accessorize this dress.

I ended up buying this dress because it was shockingly comfortable and actually felt like it was flattering as I rarely wear dresses or form fitting clothing of any kind. My only concerns are showing too much of my chest and clavicles and potentially being over dressed for the occasion? I was thinking I could thrift a stole or buy a shawl to cover up a bit more. My biggest questions are:

1. What to do for shoes and bag
2. Can I wear gold jewelry with this or do I need to go with silver?!
3. Did I totally miss the mark with this dress??

My husband works for an advertising agency if that's at all relevant and will be wearing a black suit with cowboy boots and bolo tie.

Apologies for the wall of text, and thanks in advance for any guidance!

Out shopping for my birthday gifts 🎉🎉

It was so hard to get everything in one pic with decent lighting so enjoy this weirdness

Just wanted to share my Thanksgiving outfit, did I do something right? Something I should change/improve in the future? Any advice welcome.
