What makes a technical sports bra different to a crop top?

With so many mass produced, pattern cut sports crops on the market it's easy to see why the women of Australia are confused about what to purchase in mainstream retail. In fact, any old design can have 'high impact' or 'maximum support' splattered all over the swing tag with no consequence.

Those entrenched in the technical Sports Bra world will consider a Sports Bra to tick the following boxes:

- Produced in cup and band sizes eg 12C, 8G.
- Independently tested in a biomechanics lab, to ensure function during activity
- Use technical, moisture wicking fabrics
- Have multiple points of adjustability
- Generally they will be made of many different elements, using up to 32 individual pieces.

Whereas, sports crops will generally be produced in XS-XL sizing, have no lab testing to ensure functionality, be produced with fashion as the major focus, use simple fabrication and be a basic 'pattern cut' design.

Why does a bra need to fit you properly?

If a bra doesn't fit, it has no chance of functioning. So choosing the 'highest rated' Sports Bra online may just leave you disappointed if the size isn't spot on. This is because the bra needs to fit firmly around the ribcage in order to best stabilise breast tissue. The cups also need to be fitted appropriately in order to best control breast displacement. Here's a bra fitting guide to help you ensure your size is spot on.

How does a bra support us?

The band that runs around the ribcage is thought to provide up to 90% of the total support of the bra. If this band fits loosely then the band will ride up and down your back. This will result in the front, 'the bust', doing the same, due to the see-saw effect. As the back rides up and down, so does the front. This is bounce, or vertical breast displacement. So it's crucial to have this band around the ribcage fitted firmly, yet not uncomfortably tight.

The shoulder straps are there to provide secondary support, or as we usually say, 'stability'. While we would be in a bit of trouble without them, they are not there to take the weight of the breast or stop it front bouncing.

Most commonly, women believe it is the underwire that provides the support, however this is not the case. The role of underwire in a bra is to shape and seperate the breast tissue. It does not stop our breast from bouncing during activity.

How does bra sizing work?

It's staggering how many women don't understand the way bra sizing works. Here's what you need to know... :)

An A cup, or a G cup is not a set unit of measurement, a cup sizes will change when the band size changes. For example an 8D cup will be about the size of an apple, but a 24D cup will be about the size of a rockmelon. As we go up a band size, the cup also goes up in size, but the letter remains the same.

Bra sizing works to allow for a system called 'sister sizing'. This means that if we go down a back size, we need to go up a cup size in order to keep the same cp volume. This means that a size 12D and a 10DD are the same in cup volume/size, but just fit differently around the back. This is the reason that sometimes the 12D's will work well for that customer, and in other brands/models the 10DD works better.

What's most important is to know that bra sizes are just a guide. In most cases we fit customers that are buying multiple products in to more than one size - every brands interpretation of sizing are different.

What causes a bra to chafe?

Chaffing is friction. Friction is caused by rubbing or movement. In order to reduce or eliminate this we need to ensure that the materials sit and stay firmly against our skin. Most commonly, if we can get a technical high quality well-fitted bra then we can eliminate chafing. However, there are times when this is not achievable.

There are other factors that can contribute to chafing, which may not be able to be controlled by the bra itself. These include sheer distance being run/walked, moisture content in the skin and the effect of other garments. Some people are 'chronic' chafers, and it doesn't matter how well a bra is fitted and selected, they will still chafe.
