Belted Floral Field Poplin Midi Dress SZ 14 - NWOT 

Architect Miranda Brooks—whose work inspires this season's florals—designed LSD's gardens at her Southampton home, so you can imagine which pieces are a personal favorite of hers.

Tailored from stretchy cotton, this dress has a sweet and simple silhouette with a T-shirt style bodice and gently pleated full skirt. Use a belt to define your waist and add volume.
