SUPPORT
Some swimsuits have a shelf bra or padded cups. Handy for extra support/modesty if you have a larger bust.
LEG CUT
Swimsuit legs are usually described as high, medium or low based on the amount of coverage they give.
STRAPS
Can be thin or wide with various back designs. Choose one that's comfortable for your shape.
FABRIC
Quality fabric will survive more wash/ wear cycles as well as fading less quickly. You may want to consider eco qualities.
Most of us will train in a mix of the pool and outdoors during the winter, but come the colder water and dark evenings we'll find the pool is our main swimming venue. If your swinsuit isn't what it once was, though, you may want to invest in a new one.
Training swimwear should be chosen to improve speed and maximise comfort,
