Today seems like the day of the Pastels O.o;;
Anyway, here’s a quick tip for Fairy Kei (though can apply to other fashions). Do not overload your outfit with main pieces that have patterns including loads of different colours. It’s off-putting and isn’t easy on the eye.
Instead try to focus on 2 main colours + white (or a different colour if you’re feeling ambitious) as this is easier on the eye, and because the white stands out more but takes up less space it allows somewhere for the eye to settle on rather than the outfit being one big pink and blue mess.
You can then begin to add accessories like bracelets and necklaces that have different colours.
it’s a noob trick, but sticking to a two or three colour palette is better than loading up on everything :D
