It's not really a bra with padding cover the neh neh type. It's
more like a singlet and the two sides are of very strong elastic
material to push the flesh to the centre. From what I understand
from the ERO's one, the chest part is not covered so the user still
have to wear a bra inside. The buckle is at the waist. Once buckled
up, the two elastic sides will push the flesh forward and the chest
will look more 3D.
Too bad, the ERO's site is down. I can't paste a picture of that
singlet here.
