Diamond, Houseki no Kuni

A young woman with pale blue hair and bangs, wearing a black romper-style jumpsuit with short sleeves and a white belt around her waist. Her legs are clad in knee-high white socks, and she has on black shoes. She is holding up her index finger to her lips as if signaling for silence or secrecy. The background of the image is blurred but appears to be an outdoor setting, possibly a park or garden, with greenery visible behind the woman. Overall, the atmosphere of the image suggests that it may be related to a costume party or cosplay event.
