Letter size is M, but I altered it to fit a size small. A fitted sleeveless mini dress in a vivid pink crepe with a high mock neckline and a curved high-low hem that dips lower in back. The sculpted silhouette skims the body without clinging and works well with simple heels or strappy sandals. Suitable for cocktail parties, date nights, brunch, and summer weddings.

Rent for $30/week. Original retail price: $238, 87% off retail.
