i think natural is always best. even when girls were make up they never want to over do it. Although they are wearing make up they generally try to keep it looking as natural as possible so why not just go all natural. its better for your skin and it is nice that she wants to show herself in her natural beauty. if she wants to wear make up though, I wouldn't make too big of a deal about it. whatever she is comfertable with but I still prefer without.
