Ra Ra skirts... All the rage in the UK

Apparently these skirts named "Ra Ra" skirts are all the rage in London/the UK. Basicly they are tiered, ruffled mini skirts. Take a gander..
I found the similar style which is being sold at Topshop on Forever 21. There's loads more to choose from (though these skirts aren't really my style to be honest).
$19.80

35 GBP (which is like $70)
