Lululemon Neon Bright Lemony Yellow Dress

Very good condition, no flaws. The rip tag has been removed and IDK what this dress is called? Fabric content unknown. Size unknown (I've looked everywhere - I don't know what it is about this brand and their stupid size dots? Do they do this in the interest of exclusivity or mystery or what?). Anyway, best fits an M-L. there's a waist tie at the back. chest 21" waist 17" length 32" Tennis golf preppy pickleball
