This wedding dress is the Poppy/4159 style by Mori Lee from the 2024 collection. I bought this dress in 2023, it has not been professionally cleaned and is unaltered. I would describe it as a Beach, Elegant, Garden wedding dress featuring 3D Flowers, Detachable sleeves, an A-line silhouette, a Straight neckline, and with a natural waist line. It comes with the original packaging to keep it preserved until you take it to alterations!
Legacy Tailor in Plano, Tx is a great recommendation if you don't know where to go for alterations.
