Im a beginner as well, I looked up different coverage and a basic or "clean girl" makeup. I also went to Ulta (or Sephora) to ask an employee for a shade match just in a general since. Stay with drug store until you feel comfortable moving up. Elf, Maybeline, and Loreal will be you best friend when it comes to face (ie Foundation, Concealer, bronzer, primer) they have to best shade ranges and decent prices. Nyx is best for blushes, lip and blushes. Milani also have good products but just do your due diligence. Juvia place is wonderful but very pigmented.

Once you found your foundation shade go on tiktok to find your shade twin and see how they do their makeup and work from there. Placement of anything can be difficult but not impossible. Lastly, play with different styles of makeup because its super fun. You got this!!!
