From Tanya Taylor Website: Designed in a lightweight linen, the Barton Mirror Dress is our signature show stopping mini and our best-selling event-ready silhouette, back this spring with new mirrored details. Features a square neckline, structured form, and eye-catching mirror embellishments. This style runs small, we recommend sizing up one size. Note from me: I originally bought a 4 but my widest part is my hips and it was visibly pulling, so I went up to a six.
