What a great mix up! Gorgeous! It looks like Blonde Vision but yours seems to have stronger stem/neck than what my BV produces. Foliage looks a bit different from BV too. So I don't think it is BV but flower looks similar to it. I don't think it is Pastelegance. Pastel has a peachy champagne color.
Here is Blonde Vision
Pastelelgance
I don't have that many bloom pics of Vanilla Schnapps to compare if yours is VS.
