On the note of simplicity, stick to hushed tones and color palettes. Parisian women are laid back, but not boring, and their confidence shines through without having to wear loud hues that desperately scream for attention.
When it comes to Parisian dressing, the simpler the better. Keep accessories to a minimum and don't overload your ensemble with too many pieces. Part of the appeal of French style is that it looks so effortless.
