Another thumbs up for suspender tights. It is worth getting good ones, dont buy from ebay, real rubbish and funny colors - the Giulia ones on the UK tights website are fab.
I hardly wear them for work now that I have focused on massage services but the mock suspender tights also look sexy if you don't intend to undress below the waist.
Suspender tights are very convenient and comfy if you wear them on nights out and at weddings and the like - hassle free loo visits (remember knickers over tights not the usual undies under tights) and no thrush - what is not to like.... worth the extra cost. I cant believe that normal tights ever sell.
