For me, this is my first part Bustier and I feel really comfortable with it at leisure. The material (95% cotton and 5% elastane) worn very comfortably. It fits like a glove, holding and will not slip. However, it forms, in contrast to the otherwise used by me underwire bras, not really beautiful neckline. So it really is perfect in my case only casual casual wear. In figure-hugging clothes I put he prefers the underwired bra on.
When a machine wash at 40 ° (according to. The manufacturer's instructions) I previously could not detect any deformation of bustiers. Clean it was doing well. However, I am not yet even come with it a real sweat. In white underwear (I wear although very rarely, but it happens) I wish personally always a possible 60 ° wash.
