en.wordpress tag question

Hi,

When I type in “jimmy choo evening bag” into google, this site is listed:

http://en.wordpress.com/tag/jimmy-choo-evening-bag/

I know this is a tag, but I like how it looks. would like to know if…

1) I can make a site that looks like this
2) How does this get created
3) Is this created by wordpress or the user

thanks,

Liz
