I relate to this! I have a different figure in that I'm small chested with a bit of a bum. But I have quite sharp strong features & as a result look much better in tailored clothing & "matchy" outfits. Always wished I could be one of those girls who chucks on a thrown together, artfully mismatched set of seperates and looks all sexy boho chic. But nope I look like I've been rifling through the local church's charity bin when I attempt it.
Did find it helpful to bring elements of tailoring into casual outfits. And also just to embrace more "formal" looks day to day because I honestly don't think they look out of place or overly formal on me. So now, I often wear things like Tailored trousers and slightly oversize blazers in casual settings. I just dress down with t-shirts, trainers, jeans etc.
Also found a go to look that generally looks pretty polished even with casual clothing. Sounds boring & probably is but most days I wear a tidy low bun/chignon with a centre part, pearl stud earrings & I minimal foundation/eyebrow shaping. I also get my lashes done every 2-3 weeks. The appointments are a faff I won't deny it. But I rarely feel the need for much make up at all when my lashes look OK, and it just makes me generally feel smarter & better about myself.
Your plan sounds great and very wise! Reading up on closet creation and the fundamentals of a capsule wardrobe in terms of colours and items was really helpful for me. I try now to only buy things that fill a gap I've already identified. And I have to be able to make at least 3 outfits with it using stuff I already own too!
If you're interested, might be worth taking a look at Kibbe too if you haven't already? It's really complex and some find it too restrictive but for me it was a massive help. It helped me understand why some items of clothing I love on the hanger make me feel awful when I put them on. When I'm shopping for clothes now there's a vast swathe of stuff i can rule our almost immediately as I know it isn't going to work for me.
I don't adhere to it super strictly but definitely take the principles of it. For me, I'm a dramatic so it's all about keeping things sharp, tailored, narrow & ensuring a strong vertical line in my outfits as well as a cohesive overall effect.
What I like with Kibbe is I feel it encourages you to lean into the beauty of your frame rather than trying to disguise it. So , most systems would class me as like a column or rectangle or something boyish & straight- then advise me to "create curves" with waist emphasis, or dress in a way that conceals my lack of boobage. But that just makes me feel silly! I'm not curvy and actually I don't think curves would look very cohesive on me anyway, its not how I'm built.
Kibbe helped me see there's actually beauty in striking, sharp looks too.
