A trendy apparel mock-up in a vibrant blue room. A dark grey t-shirt hangs from a black metal clothing rack, featuring a graphic print of the "SERUM N°1" bottle with botanical text. The room is styled with modern neon accents, including a long orange light bar on the wall and a glowing neon sign in the shape of a serum bottle. The lighting creates a clean, commercial, and youthful retail atmosphere.
