1.1) Know what colours favour you. Five colours that favour any kind of skin: red, white, eggplant, emerald green and blush. More info HERE.
1.2) Mix up to 3 colours at most.
1.3) Never wear only one colour, unless the pieces have different textures.
1.4) Darker colours on top make you look slimmer.
1.5) Lighter colours on top make you look younger.
1.6) If you’re wearing silver or golden accessories, they don’t count as one colour of the 3 ones you’re allowed.
1.7) Generally black or white don’t do either, depending on the rest of the colours.
1.8) Be careful when trying to combine make up with garments. A neutral/natural make up is generally a better idea.
