J. Crew Tiered Denim Square Neck Dress. Worn only once! Size 6 A quintessential '90s look, we gave the denim dress a modern-day upgrade. For this style, that means sweet tiers (in the skirt), comfy smocking (in the back) and a streamlined, squareneck cut (at the chest). By buying cotton products from J.Crew, you're supporting our investment in Better Cotton's mission to help cotton communities survive and thrive while protecting and restoring the environment. This product is sourced through a system of mass balance and therefore may not contain Better Cotton. Cotton. Side zip. Machine wash. Import. Item BG514.
