This first look is what I suggested for work - I wasn't sure what Lauren preferred, so I chose three work friendly shoes: boots, wedges, and heels. I paired the dress with some colorful coral (big for spring!) earrings and Lauren also mentioned that the tie is removable so I suggested perhaps wearing a more structured belt (see widget for some cute options).
The next look is more for weekend - brunch, shopping, etc.
If you prefer, you could change out the heeled sandals above for flat sandals, flats, or a strappy wedge (or a different heeled sandal). You could also add some different jewelry, here are some earrings that I thought would look cute.
