This is a gorgeous dress.
And, your dilemma is mine, and that of all fair haired women who want to wear lighter coloured dresses but live in a cold climate!!
Seriously, I have tried various options. Nude sheer. (Okay...but hard to get the right nude and not very practical when you have a cat). Nude microfishnet. (Also okay...but the ones I have are a bit light for my complexion, they are not all that warm, and I don't like how they feel on the bottom of my feet.) Light coloured boots and booties...helpful, but how many of us have light taupe knee high or OTK boots? (Brooklyn excepted.)
I do think that is probably the best bet unless you want to go more casual over jeans.
The thing of it is...black or dark (navy, ink, charcoal, dark burgundy) can feel so heavy and unbalanced when you are a blonde. I don't know what it is. It's easy for anyone with black hair. Put on black boots and *boom*!!
I'm about to go through this whole thing again now that my hair is silver. I think that black may actually work better than before (YAY) but lighter is still going to be better on the whole, so it is a whole exercise of re-jigging.
