Start By Finding Your Size
In order to find a well-fitting bra, women must be properly measured, preferably by a professional. The most common mistake made when buying a bra is assuming that one size fits all. Not only does this often lead to ill-fitting bras, but it may also prevent women from realizing their correct size.
If you find yourself wearing the wrong size, then you can end up with a bra that doesn’t fit you properly. Wearing a wrong size bra will not only make you feel uncomfortable but also it may cause health issues like back pain. Trying on the right bra size can prevent this problem and at the same time it may ensure that your breasts remain perky for years to come.
For this reason it is important to measure yourself frequently. If you haven’t check your size in the last 6 months, then you should start measuring yourself in the first place.
