A padded bra is tailored to make your chest appear bigger. As its name implies, it is a type of bra which is padded. The padding material of the bra can either be water, foam, or gel.
A push-up bra works by pushing your breasts up a little higher. In turn, it gives your chest a more rounded look.
Ladies with small breasts often use padded bras, while ladies with sagging breasts often use push-up bras.
Both padded and push-up bras enhance the appearance of your breasts.
