dorothy perkins have got some nice knickers in they have cutey ruffle ones and ones that have a big bow on the back. obviously they don't have loads of ruffles but for the price you can't really complain. they also have this which i am planning on buyins as soon as i have the funds:

Purple pinspot vest/shorts - Vest & short sets - Lingerie & Nightwear - Dorothy Perkins

how cute!
