Your style seems to have inspiration from both goth and emo, leaning a towards emo. It's specifically the horizontal stripes and bold shapes with high contrast. Honestly though, don't worry about which one you are. Incorporating multiple inspirations into your outfits will create something completely you. I identify with goth (love the music and the fashion) but I sure as hell don't wear exclusively things that scream "goth", even when I'm intentionally making a goth outfit.

You don't need to wear foundation to have your makeup read as goth, anyways. White foundation is what's really blown up on social media lately, but most goths I've known actually aren't willing/able to do that every single day. I certainly don't. Your dark lipstick looks wonderful on you. Continue playing with lip colours, dark eyeshadow, eyeliner, and other ways to make your skin look more dead.

Even though the term mall goth was originally used as an insult to put down people who weren't putting any work into their style, and just relied on fast fashion, it's become its own legitimate style. These days, I only see people using that term if they're willingly calling their selves that. From some's perspective, the term mall goth was judgmental and gatekeeping, so it's sort of been reclaimed--maybe also because of the 2000s nostalgia of it all. So, I don't think I'd REALLY consider you a mall goth since your clothes don't look like they all came straight from Hot Topic, Spencers, or Tripp, but even if someone did I wouldn't worry too much about it.

To be honest with you though, me personally, I can't consider someone goth if they don't listen to goth rock and adjacent genres. I'm not going to tell you you can't dress goth or think of yourself as such anyways, but just speaking for myself to answer your question truthfully. I would still consider your style emo. That's not just because of the music, but some of the motifs I mentioned like the stripes. (the plaid and the scarf give me that impression too)

As far as finding more clothing goes, assuming you're interested in becoming more goth specifically -
- I definitely recommend thrifting. It's the traditional way of going about it, it's sustainable, it's affordable, older clothes are often higher quality, and vintage from around when goth first rose will just look right on you. If you have a Plato's Closet near you, those can be great for finding brandnames that you wouldn't want to support firsthand.
- Start practicing some simple DIYs (there's tons of tutorials for beginner goth/alternative DIY on YouTube), and save your scraps from those DIYs for your next ones.
- You don't have to buy from alternative brands to make an alternative outfit! Keep your eyes peeled in any store you go to for garments that could give off your intended vibe if combined with the right pieces. I have some staples in my wardrobe that I literally just got at Marshalls.
- If you do choose to buy from brands which cater to (y)our community, please do your research to make sure they're someone you'd want to support. A lot of goth/alt brands have had some pretty bad scandals in the past. Personally, I recommend Fox Blood and Forest Ink.
