How can a SD wear baggy clothes?

Whenever I try to wear baggy clothes I end up looking like they are too big for me, and I lose vertical line and structure, as if my body was drowning in them.

I want clothes that look relaxed, casual and covered, but most of the SD recommendations are too formal, and wearing tight clothes usually makes me uncomfortable.

If it helps, I am almost sure my essence blend is ethereal -dramatic - romantic, but I want it to simulate a more natural essence while following my lines.

Please help <3

Edit: thanks everyone for the recs
