Masc/andro business casual

So I got a new job and I have to wear business casual. Business casual never really made sense to me because I always feel that I'm either under or over dressed and I can never quite hit the mark. I don't like frilly stuff or skirts, so I went and bought a few blazers, collared button downs, and dress pants.... but now I feel that these outfits are TOO professional...... help??? Any ideas on outfits? I'm not super masc but pretty androgynous
