Unfortunately, there aren't really great pastel palettes out there. Sugarpill recently released the little twin stars collab which might be up your alley, but as with all pastels, looks mildly anemic in color in initial reviews, but then again, most pastel eyeshadows are helped with a white base.
As for lolita makeup, I honestly just look at Korean tutorials these days. They fit my eyes and the less trendy ones have that cutesy look that flatter my asian eyes as well. Lolitas tend to have really sloppy makeup tutorials, Misako included ugh.
