I hopefully got her close to Selena Gomez but I will update later if she still doesn't look like her. You can find Selena in The Bannered Mare. Nothing much about her, just she looks or almost looks like Selena Gomez and she's marriageable. Compatible with UNPB and CBBE.

Know issue: Haven't found one yet.
