1. Navy Birdseye
2. Dark Blue Plaid
3. POW Flannel
4. Nailhead (wrong size)
Thats...all Ive got.
Here is a suggestion: go to BnT and do exactly what they tell you.
Seconded on the RAF blue (maybe in fresco since you're in DC).
The B&T instagram is full of good examples in that color. I might just show them this pic and say "one for me too, please."
