How can i look put together and pretty like these girls?

this is a group of friends that i am sort of aquainted with. i know they all put a lot of care into how they look and a lot of effort. i feel like i look sloppy, so i want to put the same effort into the way i look. i have thin, wavy auburn/brown hair. brown eyes. sallow pale skin with dark under eye circles. and not really any weird features or anything. any hair style, clothing, and make up tips? remember i want effort similar to theirs:
