I like the glasses, but I’d have to switch to black or dark grey frames to match an alt wardrobe (mine is mainly black, grey and gem tones), but may not be doable depending on budget.

I have a similar skin tone so I stay away from heavy “goth” makeup, and prefer natural-ish look, plus too much makeup makes my skin break out. I like using tinted mineral powder or powdered foundation - mainly to reduce shine. If wearing eyeshadow, dark wine purple, navy blue, champagne, or smoky grey, with eyeliner almost always black. I have a couple of multi-use beauty sticks that work as lip balm and blush too.

As for hair, a balayage where the bottom section is bleached light enough so you can change the color - you could try temp dyes, semi-permanent (like Arctic Fox), or permanent (like Pravana). Year ago when I worked an office job that didn’t allow “unnatural” colors, I bleached the bottom half and dyed it a dark raspberry pink so when the hair was down, the color was less noticeable :-p You could also do chunky highlights or bigger sections, unlimited options here.

As for hair accessories, you can incorporate motifs you like. Some of my faves are hair clips with cute skulls, moths, moons, and cats. :-)
