What to wear to the opera

Hello dears,

On Saturday I am going to see "The Marriage of the Figaro " with my friends.  I'm seeing an opera for the first time so I have had problems to find something proper to wear at the opera house.
I did a little googling and it looks like it's okay to wear pretty much anything when you go to the theatre, ballet or opera. I'm kinda speechless. I thought the idea is to wear a cocktail dress or a suit. I mean something better than what you would normally wear. It's totally okay to wear jeans when you go to see a movie, but NOT in an opera house!! No way.

Basicly I found myself in a situation where I didn't had any little black dresses or cocktail dresses. Mostly coz I just sold my old ones coz they were a bit too revealing. I have noticed that when you get old you don't wanna wear anymore too short dresses. It's simply tacky.

So I bought a blank cocktail dress and I gonna wear it with red shoes. I was thinking something simple but classy. Black dress, red shoes and a necklace. That should be enough. Or what do you think? What would you wear?

I will write about how was the opera later this week, then you will also see my final outfit for the opera.

Till next time!  Ciao!
