mismatched black -- business formal attire?

kind of an SOS post, kind of a looking for general fashion advice post hahaha for an upcoming work interview:(

I've heard it's a fashion faux pas to wear mismatched blacks for your top and bottom, as it looks like you're trying to emulate a suit but you're failing really badly 😢 -- at least that's the case for men's business formal attire. there's not much chatter about women's business Formal outfits online :( i'm a modest dresser/hijabi too, so it's tougher 😅

re: the picture: my fabrics I have on hand:

top: dark grey, cotton blend trousers

middle: black blazer (cool toned)

bottom: black structured flared pants (warm tone)

i'm figuring out what's the best course of action to save my mismatched blacks! would it be ok to go ahead? should i wear the dark grey bottoms with black blazer at the cost of maybe looking more business professional instead of business formal? 🤔

anyone have any experience doing so, what do *you* wear when the dress code calls for business formal?

thoughts welcome!

edited to add: interview is for an entry-level management associate in customer facing industry - luxury brand/hospitality. :)!!
