You should change your bras every six months to sustain proper support and fit. Remember, the better your bras fit, the better your clothes will fit, and the more confident you will feel.
To illustrate my point, take my “6 Month Bra Challenge“.
Purchase two of the same style / size bras. Put one away and use the other for six months. At the end of the six months, pull out the unused bra and observe the difference. You will be amazed at the wear and tear your bra goes through! But don’t just take my word for it: try on that new bra and compare the fit to the older bra. Feel and see the difference!
Your bra support should be 90% band support and 10% shoulder straps! That’s why it is very important to get properly fitted. See my bra fit guide by clicking here.
