The complication comes because of the way bra sizing works

My conclusion is that I will have to change my fitting advice. I believe the backs on these bras are too much on the small side, although the cup size is correct. Therefore my recommendation is that you should try a back size larger than your normal bra.

The complication comes because of the way cheap lingerie sizing works. When you go up a back size you also go up a physical cup size. So a 36D is a back size AND a cup size larger than a 34D. Sounds a bit odd - but it is actually correct (and probably explains why so many women are wearing the wrong sized bras).

It is only the back size that is a problem - the cup seems to fit true to size. Therefore to keep the correct cup size in a bra that is one back size size larger you will need to go down a cup size.

Just remember the phrase "up a back size down a cup size".

So - if you are buying Shock Absorber Bras then my advice is to go one size up in the back, and one size down in the cup. This will give you a bra which is one size (2″) larger in the back, but with the same physical cup size.

So, if your normal size is 34D - then you should be trying a 36C.

This will result in a bra which is more comfortable, and that you can wear for longer periods of time, but has the correct level of support in the cups.

Inexpensive bras are not the devil

Low-priced Bras have a bit of a bad reputation when it comes to quality. They are considered to be inferior to their more expensive, brand-name counterparts, less durable and generally not as well made. And although this may be true in some cases, you may be pleasantly surprised by the quality of some of the more budget-friendly bras and lingerie.

It's always helpful to try on as many different bras as time permits. Mixing it up with a few low-priced choices and a few pricey ones will often reveal one or two 'diamonds in the rough' that you previously might have over-looked simply because of their small price tags.

Don't banish high-priced bras completely

It's also still possible for you to save money as well as indulge in your favourite brands by buying a select few 'special' bras, like an expensive convertible or minimiser bra, for those times when quality and reliability are not up for negotiation. Having more affordable bras for everyday wear can spare you any great financial outlay when they inevitably need to be replaced, although you'll probably be a little shocked when they last longer than you expected.MORE:cheap sexy lingerie
