WWW - can highly recommend sandals from Clarks called Rosabella - I have them in the bronze colour and also in white. They are like slippers comfort wise but are sequined so have a bit of glitz. They look fabbo in the sun and I'm living in mine worn with skirts or jeans. Look particularly good with tanned feet!!
Have you tried H&M for skirts? - I've got a couple of really nice ones from there, one long, one just below knee. They are patterned but look really nice with a plain vest/shoestring top. I've been living in floaty skirts, glitzy sandals and Tesco £5 secret support shoestring fitted vests (might not be ideal for those with decent sized norks though).
The other skirts I've got are a couple of cotton ones from Monsoon (last years sale though!), just below or on knee. Also got a nice one from Tesco - white with blue thin stripes in it going in different directions - really floaty and cool.
