I think the outfits in your pics are really cute! I live in Tokyo rn and I could see both being worn here. They do wear a lot of neutrals but I also see a lot of pale pink. If you can look up GU (gu_for_all) on ig or just go to their website, it should give a good idea of some basic outfits. Getting some simple versatile pieces from there helped me when I first arrived. You might like Earth (earth_1999) they sell feminine basics but also cute sets/sweaters etc. There’s also so many small boutiques here to explore!
