Need ID for dealer-made outfit

I got this dealer-made dress from Mandarake, and strongly suspect it's the outfit for a specific character, possibly from a gacha game:

The topmost item is a headband with silver/pink cat, fox or wolf ears, whereas the one below likely wraps around strands of hair on each side of the face. It's all sized for a DD (not a DDdy).

Based on the colours and design, I guessed it might be from Azur Lane, but my research has not yielded a match yet. There is no manufacturer label, but the materials are quite good. Any guesses?
