Sarah's outfit

Does anyone know the name of her outfit? I could swear I saw someone walking around in it, but they were gone before I could examine their look. All I can glean is that it was called Heart Breaker in the Japanese version.

It is Heart Breaker, but it was part of the Mission Pass, so it is unavailable on the Personal Shops.

Noooooooo can't believe I missed it...oh well, thanks
