Here are some good ideas for how to care for your binder:
Hand washing will be the best care, however, you can put your binder in the washer in a delicates bag (you could do either warm or cold water) for example: hand wash warm, hang to dry; OR machine wash cold or warm, place in dryer on low heat for a short time. If you are washing it by hand,you can use a stain remover around the edges when it builds up with sweat/small dirt/makeup--these marks should come out easily. We recommend washing it when you notice it begin to pick up sweat/deodorant smells. You can also have your binder dry cleaned if you prefer not to deal with the hassle! :+P
The rules for drying: hang to dry or put your binders in the dryer for about 7 minutes to sort of fluff and tighten them up once they've dried over night. :) It's really up to you, if you want you can wash and dry in the machine every time, but be aware that it can reduce the life of the garment if you do this.
