There is lots of confusion about what a corset is these days! Things get muddled and confused, so we here at Waisted Lives have decided to make a quick comprehensive guide.
This is not a corset. This is in fact a longline bra. Defining characteristics: It is a bra, made of traditional bra materials (power mesh, often underwire, has separate cups, hook and eyes in the back, etc.), and extends longer than a regular bra, generally just above or to the natural waistline.
This is not a corset. This is a bustier! It is a piece of lingerie that is actually quite lovely! Generally plastic boned, usually made of similar materials as bras, such as power mesh and lacy goodness.
This is not a corset. This is actually a more confusing piece of clothing, as it has not been around nearly as long as anything else here. It is often referred to as a bralette or a crop top (although it differs from traditional baggy crop tops with its inherent structure). The main difference between these and longline bras is that longline bras are considered underwear, while these are considered outerwear! Although you can certainly wear anything however you want, that’s the fun of fashion!
a worthwhile read if you don’t understand what a corset is.
