ASOS "Pieces" Petite Floral Tiered Maxi Dress

Pieces floral tiered maxi dress, purchased from ASOS. Thin material, perfect for spring or summer! ‼️Please note: this dress is advertised on the ASOS website as a petite size small. However, the tag says only size S.‼️It's too big and too long on me, fits more like a size 6. I included the stock photos of the model. The model is 5'3" and is holding up the dress while wearing a slight platform shoe, so I think someone between 5'3" - 5'5" could wear it and it would still be floor length. Brand new without tags, unworn, not laundered, no known flaws. My measurements for reference: Bust - 34 Waist - 27 Hips - 36 Height - 4'11"
