Lots of redheads on here today - me too, a natural red, with boosting from Clairol when I worked for them many years ago!
I stopped coloring my hair about 10 yrs ago and have turned out to be almost white (at this age) with a hint of goldish shimmer. It goes with my skin which is a warm beige.
I’ve been a lifelong (adult) wearer of black clothes (professionally and personally) with a touch of color here and there. It looks really good with my new look, but I’ve taken new interest in navy- it’s softer.
Going gray DOES CHANGE your look when it comes to clothes- and you must consider your skin tone - colors I never wore before now look fantastic - (certain) beiges and grays, blues, golden and bronze shades, along with peach and corals. A few greens.
Baby pastels, reds, mauve/pinks/purples… forget it!! Total white is a no-go, unless under black.
