Miki Hoshii, Idolmaster

The image features Miki Hoshii from The Idolmaster in an elaborate pink and gold costume, with long blonde hair and a golden bra top adorned with small gold coins. Her outfit is complemented by matching shorts, thigh-high socks, and boots, all covered in sequins. She wears a gold coin necklace around her neck and has a white fur trim on the sleeves of her jacket. The background appears to be a hallway or corridor, possibly at an event like a convention or cosplay gathering, with people milling about in the distance.
