If I had to describe what my go-to "uniform" is, it would undoubtedly be some variant of (blazer + stacked heel shoe) x black + statement necklace. Ever since I started being a lot more intentional about buying clothes, I've found that a black blazer is a must-have, along with a comfortable but classy shoe. If you have those things, the possibilities are endless.
All it would take to make this outfit office-appropriate would be to ditch the ripped-up crop top and oversized necklace and add a blouse and some minimal jewelry. Blazers, man. So versatile. If you're a youngin and looking for your first job, you gotta grab a blazer. You don't even need to spend a lot of money on it: For example, check out this one from Forever 21. A boyfriend cut looks great on every figure and since it's so cheap, you can definitely spring for those alterations.
Finish the look with some bold jewelry and you're set! I love unexpected combinations so to add some personality, I paired this business-friendly blazer/pant combo with a ripped tee. I was a sucker and bought it from Urban Outfitters (don't judge me, it was on sale) but if you're the frugal type, here's a DIY. (Not exactly the same but there are some great ideas on there!)
