Madonna vs Kylie

So Madonna has revealed in an interview with the International Herald Tribune that she's thinking of doing a 25 year retrospective showing off all her old clothes and stage costumes. Uh, didn't someone do this already (like... Kylie)? Ok, poor Maddie is a bit Johnny-come-lately in the originality stakes but actually, we'd rather see this than Kylie's lacklustre attempt at the V & A. At least Madonna actually set some trends (who do you think invented leggings?) but what trends did Kylie start? Frizzy perms and dungarees... not good enough! What do you think? Should Madonna do a retrospective or is she jumping on the bandwagon?
