7 Rules of Sports Bras
Follow these tips from bra expert Susan Nethero who says that less than a quarter of all women wear the right size bra:
1. Look for sports bras that come in cup and band sizes rather than just small, medium or large; they fit more precisely.
2. Choose bras with strategically placed seams and stitching, which help cushion the breast.
3. Pick high-performance fabrics that wick away sweat to minimise chafing. [The blurb on the bra's label should tell you it does this].
4. Own a variety of sports bras for different levels of activity. When in doubt, choose a higher-impact bra for a lower-impact sport - not vice versa.
5. Get fitted by an expert. You can find bra fitters at most department stores and Bras N Things.
6. Before buying, jump, swing your arms and move around. If a bra pokes, runs, slips, jiggles, constricts your breathing, or bulges, put it back. Also, it should fit on the first hook; as it loses elasticity over time, you'll need room to tighten it.
7. Rotate your bras and wash them regularly to get at least a year's use out of each one.

Keep it clean, ladies
A good sweat sesh does wonders for your body, but for your bra? Not so much. Chemicals in sweat break down Lycra, making it more likely to droop under pressure. To extend your bra's lifespan, launder it after every workout: hand-wash in cool water with a mild laundry powder. To kill stinky odours, sprinkle white vinegar on it before washing. (Don't worry, you won't smell like a fish and chip shop.) If you do toss it in a machine, use the gentle cycle and enclose it in a net bag with the bra's hooks fastened. To dry, always hang it up or lay it flat; dryers ruin elastic.
