A lot of their stuff is pretty expensive, as you might expect (£80 for an umbrella, anyone?), but there are a few lovely pieces for relativly cheap, and for UK lolis especially it's a nice source of pretty parasols for a bit less than importing from Japan. The quality (from what I saw in HN) is much nicer than those horrible Battenburg lace parasols on ebay, and for not much more.
Here's some good stuff I found:
http://www.brolliesgalore.co.uk/acatalog/copy_of_Sophia.html <---nice £20 parasol/umbrella in white and antique white. I've not seen many parasols in a dark shade like that.
http://www.brolliesgalore.co.uk/acatalog/Amore2.html <----a nice ivory coloured, frill-edged parasol that's £15.
http://www.brolliesgalore.co.uk/acatalog/copy_of_Lolita_Parasol_-_Cream.html <---this one's actually called the Lolita Parasol...but it's close to £100 and not actually that nice ;-).
There might be some other nice stuff that I've missed, too.
