Looking to mature my wardrobe

I'm looking to mature my wardrobe a bit. Generally I dress quite gothic, go to brands are Eytys, Alyx, Stone Island Shadow Project, Maharishi, Vivienne Westwood and custom pieces. I've been looking at brands like Hyein Seo, Final Home, Issey Miyake, Jacov (specifically jackets), KodyPhilips (specifically trousers) and a few others. All in all I'm looking to focus on outerwear and trousers. An example of trousers would be Hyein Seo Cinch Trousers. Also enjoying the Hyein Seo outerwear, specifically the puffer vests. Final Home jackets are also quite fitting of the style I want to move towards. I tend to focus on wearing boots in general, however I wear a lot of airmax (eg Spiridons, tailwinds, Kukinis) on nights out. Anything that would go with both would be a plus. Specifically looking for Black/Acid wash black clothing. Sunbleached black also works. For things like hoodies I'm looking for heavy boxy cuts. Tending to go with a more cropped fit these days to accentuate leg length. Trousers I look for a wide leg fit, generally baggy (eg eytys Scout trousers, Eytys Benz/Titan jeans). Distressed/spiked also works. I'm based in the UK, not opposed to spending £400-500 for a pair of trousers and up to £900 on outerwear . Sweatshirt/Hoodie budget similar to trousers, maybe slightly lower due to falling out of rotation quickly. I'm just above 6'1 and around 145lbs. Wear a w30/L32, M/L depending on the fit for outerwear and sweatshirts. I've attached a few reference images if its any help. Thanks in advance
