Recommendations for overcoat - not blazer - for interview

Basically Title

I have these pants, black wide leg. I plan to pair it with a simple bodysuit top, again black.

My issue is over layer. I hate a blazer. I have a large chest and wide shoulders, I feel like they're always tight around my back, I can't move, and it makes me look bulky.

I wanted to wear an oversized cardigan, but the Women's engineering sub confirmed it was too busy, bright, and casual for a final interview.

Would a more form-fitting cardigan be appropriate? what other options should I be looking at? Any insight would be helpful. I struggle with "corporate" dress as I've mainly worked in manufacturing environments.
