Runs slightly small. I’m normally a small and wore a medium & was comfortable. Super flattering. Worn once & in perfect condition. Steel blue stretch is fabric. Posted from website: This fitted midi dress is as flattering as it is comfortable! Ruffled to perfection, this steel blue dress isn't your everyday midi! A square neckline and tank top straps lay the foundation for a simple silhouette, while dainty details including a slit to elevate it. Show up and show out at all this season's events.
