Looking for a bustier, corset or combination bustier corset? Do you know the difference between a corset and a bustier? Corsets are mostly for cinching the waist and lifting the breasts in a more extreme way than a bustier. Bustiers are fashioned after corsets, but are made to be more comfortable. Bustiers still lift the breasts, but with much more gentle cinching. Basically bustiers are better for club wear and being comfortable for longer periods of time. and corsets are better for times when you want your waist cinched as small as possible, and not planning to wear it for long durations of time.
