What products do you use for Pien makeup?

I have trouble with choosing products for my makeup. I was thinking of buying flower knows palette and maybe other stuff from flower knows but it's a bit expensive for me so I need advice. Do you guys recommend flower knows? I'm open to read a non-Jirai Kei girls advices too cause I'm also wearing lolita fashion♡

So is flower knows a must have? Or maybe which products do you recommend except flower knows?

(Pls don't be rude in the comments)
