What jacket with this cobalt blue dress?

[Sigh81]

I work in financial services. I never wear this dress (see pic) because no idea what jacket goes. But it is lovely. What blazer would you wear with it out of:

1. Navy blazer
2. Black blazer
3. (possibly too edgy for my offices even if the shape and neckline together are 👌) a yellow Stella McCartney blazer

They are the only blazers I have and am trying to "shop my wardrobe"... all help appreciated!

Oh, I also have a cream brocade blazer which am assuming is definitely out.

I have a dress very similar to this and I wear things under it. For example I have a body shaper slip that I wear or a stripy long sleeved top.

A white blazer or a fake Chanel-esq box cardigan. Boucle style. Zara are good for them.

White blazer!

Though given your brief I'd say the navy you currently own.

Great dress ! I say a grey blazer or if you really want to stand out a coral blazer?

I have identical dress and wore with a black blazer which looked really nice 👍

Try a white shirt underneath.
