Can you wear a black sweater with brown shoes

I was wondering if I could wear a black sweater with brown loafers.I have two high quality black sweaters, a v neck and a cardigan. They are both very merino wool, and I’ve been wearing them with jeans, dress shirt, tie, and my brown loafers.I want to know if it is okay to wear my black sweaters with my brown loafers.

How to rock sweaters

How do I wear sweaters with a collared shirt under it? I want a classy and sophisticated look but don’t want to look fruity or too old, since I’m just 18 old. Thanks for your help.
