Open your underwear drawer. Locate any greying, faded, washed-out or tired-looking knickers/pants/thongs. ALL OF THEM. Yes, even that pair that were once a little bit special. Place all of the sad and unloved underwear in the bin. Gradually replace with pretty, silky, colourful, sexy, lacy pairs of knickers that make you feel truly wunderbar. The acid test? If you pop them on and feel like dancing around like a loon, then they are probably amazing enough. Go for something completely frivolous, slightly impratical and eye-wateringly expensive from Damaris, La Perla, Myla or Agent Provacateur. Or all-over lace Brazilians. Or girly patterned cotton briefs from M&S. Whatever you choose, make sure they make you feel gorgeous.
