Freya are revolutionizing their sports bras all the time. They've even cup up with proper swimming costumes full of support and much nicer than anything else you see.
Panache have also just introduced their new sports bra which comes in some great colours and is a little bit more padded than the Freya. They have a fab blue, red and white edition coming out for the Olympics! I will try this sports bra in the future so I will keep you posted,
