[ Swimming & Diving ] Open Question : knee length body swimsuits for women?

I need a knee length body wet suit, like the one that pro swimmers wear.. i've tried rei, and most sports stores around me, either tehy dont sell them or they are very expensive.. is there any online stores that sell them, for not that expensive.. also i have tried pro swimwear, which is located in the uk.. but they never reply to my emails.. so im a little hesitant to order from them,,, if you know anything about them that would be great!! thankssss
