We need to work, as well as take a break. So is our breast. It need exercise, and also need to get freed some times. A good bra is needed when you work and do exercise. But it will only last 10 months at most even if you take good care of it. Here are the signs that you should get a new bra before its life span:

1.The bra straps slide off your shoulder very often
The straps will be loose after wearing many times. When this happens, your bra will no long give enough support to your breast.

2.The cups move up very often
Cups can change their shapes with time. It is very common that they move up often, especially when you are walking.

3.There are red marks on your back
The straps will become tighter and tighter after each washes, which is the cause of read marks on your back.

4.There are red marks below your breast
The shape of the underwire can change too, even if it is made of metal. Use bra washing ball every time you wash your bras to protect the underwire.
