How to measure yourself: bust around the fullest part, waist at the narrowest point, hip around the fullest part, with the tape snug but not tight.
How to measure a dress you own: lay it flat, measure across the chest one inch below the armhole and double it. Compare that number with the bust column.
Fit: True to size

Margaret and 14,000+ others are enjoying the comfortable pieces of our Boutique.
Clearance pieces are not restocked: once a size is gone, it is gone. Popular sizes sell out first and stock is moving quickly. If you can still click “Add to Cart”, your size is still available.
