You are lovely, OP, and your baby is beautiful!
I think your colouring is somewhat bold, lucky you. It means you can take black, white or off white and, to the extent you like, some bright colours. What you’re wearing in the photo suits you but I think a pop of colour around your neck would do a lot for your face.
What that colour should be, I am not prepared to say. I can’t tell whether your skin tone is warm, cool or neutral.
Does gold or silver tone jewellery suit your skin better? Matte, textured or shiny? Which stones? My vague understanding is that most of us lean towards either clear or sludgy colours, and mostly we favour either blue tones or yellow tones and either orange tones or pink tones. Of course that’s quite simplified: eg my colouring likes dusty blue, forest green, deep rose, soft red, navy and rust, also black. All of these are somewhat sludgy and even my ‘good’ rust has a bit of blue in it.
I really like your lip colour in the photo. But possibly because it would work for me! (I do think you look good but could be biased.)Perhaps you could look for colours that work with it. If they don’t suit you, maybe this isn’t your best lip.
If any of this rings false , that’s very useful in itself. Your intuition is a great guide. You just need a starting point.
I hope you can have fun with this
