Can you find either a knock-off or something like this?

i found this adorable underwire bathing suit top, but its 70 bucks! ahhh! i can live with paying 45 for a top maybe a little more but something just like this Betsy Johnson bathing suit wouldd be awesome.......http://www.everythingbutwater.com/browse/products/betsey-johnson/rockin-robin/38089+2113392+333.html
