If you're intending to buy quite a few things, buying them from volks is alright but you can find cheaper deals at other places. Also you may want to buy a bodysuit for your doll to prevent darker clothes from staining. Or keep your doll in lighter clothes.
/jp/ doll threads are also pretty common though they deal more with dollfie dream and other vinyl options so you can always ask them about more information as well; they're nice and welcoming over in that thread too.
