It’s nice mixing baggy/less structured silhouettes with tight ones. I usually always variate because I find it makes for a more interesting look. I got this blouse in a large to make sure I could pull off the look I wanted effectively. Even still, I think it would look great with a pair of MOM jeans. That may be my next step…
