Alexander Wang has my favorite T by Alexander Wang dress on sale in four colors (black, Sienna, Sage & desert) for $105:
I have two now, the sienna in a size medium and the black in a size small. This is the most amazing dress – it drapes wonderfully and it’s so easy to wear. I feel like the small fits a bit better for me, but if you have a larger chest, you might want to just size down one size.
Love these. I have one and need another.
