A mirror selfie depicts four young adult females in an indoor setting

A mirror selfie depicts four young adult females in an indoor setting. The subjects are dressed in formal black attire. The female second from the left is sticking out her tongue and holding a stemmed glass containing a light-colored beverage. The female in the center is taking the photograph with a dark-colored smartphone, obscuring her face. The female on the right is smiling subtly. A fourth female is partially visible on the far left, reflecting an off-the-shoulder black top. The environment is a light-colored (off-white) wall with a large, round mirror framed in dark wood. To the left of the reflection, a green emergency exit sign with a white running figure and a downward-pointing arrow is mounted, with a white rectangular device above it. A white paneled door is visible on the left and partially on the right of the reflection. A dark-framed picture hangs on the wall between the two visible doors. The setting appears to be a hallway or restroom in a public or semi-public establishment. The specific location within Vila Nova de Gaia, Portugal, cannot be precisely identified from the provided visual evidence.
