I'd like something to keep my feet warm and toasty - but that don't make me look ridiculous.
Last year I had furry boot things which were fab as they kept my ankles warm too. DP and everyone hated them... but 'normal' slippers don't keep my ankles warm so a boot style works best for me. I really don't want to go down the slipper sock route as they remind me of being a very unstylish teenager - correct me if I'm wrong and they are back in vogue!
I bought Ugg outdoor boots copies to wear indoors as slippers - but pop outside to feed the chickens in them too.
I have some pretty flowered satin mule type slippers which MIL bought me ages ago, but I try and save those to take away with me as heavy wear would ruin them. I wear them if we have people round for dinner too
Other than that I have ballerina type slippers, but have lost one in the house somewhere .
I don't think slippers can be particularly stylish/sexy though, I go for cosy and not too little old lady...
