Lululemon Flow Y Bra IV Twin Stripe Black/Black Size 4 Style Number: W2476S Simplicity is a beautiful thing. We made this bra because we wanted a seasonless classic that we could wear under any tank, for every activity. We gave it a COOLMAX liner and added mesh in strategic places so we can blow off steam when we work up a sweat.
