To Scarf or Not to Scarf?

This grey sweater dress might be the most versatile thing ever! I have so many ideas for mixing it up, but I feel like it could use some color somewhere. Any ideas for accessories that pop?

New:

Dress: Pure + Good Gertrude Ribbed Dress. I'm not much of a dress or skirt person, but this one is long enough that I don't feel exposed, comfy enough that I want to wear it, and versatile enough that I'd be an idiot not to take it with me.

Scarf: This lovely grey ombré pashmina was a gift, but I've linked a similar one - complete with fringe!

Refresh:

Belt: Kate Spade

Shoes: Blondo Villa Waterproof Boot

Necklace: Black Tahitian Pearl Pendant Necklace (similar item linked)

I feel like this necklace gets lost with the grey dress. What could I wear that would stand out a little more?
