When mesh is incorporated into the fabric of an article of clothing, it is usually to add a touch of sexiness to the garment, and it certainly works. Mesh being see-through, it can expose some skin without revealing too much. Depending on how daring you want to be, some models offer only small touches of mesh, while others reveal large portions of your body, be it the back, legs or waist.
Of course, clothing of this type is only appropriate in certain places. In some dance clubs, where people let loose and are more daring, clothing that features mesh is fine. But this is obviously not an everyday garment. As well as how much skin you want to expose, you’ll have to know which part of your body you want show.
