You are beautiful! Gorgeous eyes and lovely shaped lips. You are a very lucky young woman!
I so totally understand the whole "looking like a clown" fear with makeup. Whenever I have had someone "do" my makeup I feel like I look ridiculous and really want to scrub it off. That said, I do like a light application to just bring a bit more balance and flawlessness to my face.
I use a tinted moisturiser (with SPF) as a foundation (you could try this too as you have lovely skin) because I hate a "caked on" foundation look; a nude shade of eye-shadow with just a smudge of darker colour around the edge; a very light plummy blush and a nude shade lipstick. The one thing I do dark is a black mascara to play up my eyes more. I like to have one feature drawn into focus on my face, mine is my eyes. Oh, and I always check that my eye-brows are not going wild. A touch of hairspray holds them in place.
In fact, Hmmmmmmm, <Katiepea strains her brain for a moment> if you are not wanting to really wear makeup at this point but are wanting to start experiment with looking more "groomed" so to speak, maybe you could try having an eye-lash tint and maybe a brow wax? You have lovely brows, it's just that I find that when I have these two things done at a beautician's, I instantly look more groomed, whether I have make-up on or not. It is not a "dramatic" as in people would say "What have you done to yourself?!" more along the lines of a subtle "Itari is looking nice today, what's different, I can't pinpoint it!"
I can also totally understand how the thought of going from black to pink could bring on a heart-attack! It would be a very dramatic change as you are so used to wearing black. The ladies have suggested some lovely colours for you to try. The first practical step would be to go to the shops and try a range of colours on in the changing rooms and see how they look. Sometimes you may LOVE a colour, but it looks rubbish on. Sometimes you may not be instantly drawn to a colour, but when you put it on.... WOW!!! (I have had this experience with purple and teal lately. Never worn the colours before in my life. Thought I'd give it a try and I am amazed!)
