The vests and tanks are oversized and loose though keeping a slim figure. Vests are tucked in to create a loose shape or tanks are made with very light, maybe silk? fabrics.
I'm loving the formal blazer characteristics, like the pockets on one of the tanks (bottom left). The neutral colours create a calm but flowy feel.
