This season's most sophisticated going out dresses all have something in common: a midi length. Great news for curvy ladies tired of the pressure to go bare-legged come a night on the town and for tall ladies whose lithe limbs feel a little too 'on show' in a mini dress. The midi dress, when worn correctly, is a flattering going out dress for every size and shape and can be easily updated to take you from secretary chic to seriously sexy lady. Here's how... SPRING MIDIS Left to right: Kelly Ewing Ashleigh Dress, £150, Emma Louise London Flying Filament Fly-Away Dress, £338, L2Mae Menara Dress, £65. This spring there's no need to worry about what the weather is doing with a rain or shine-appropriate midi dress. And in sumptuous silks, sunny colours and easy-to-wear shift styles there's a style and shade for everyone. RETRO MIDIS Left to right: Kate Fearnley Holly Polka Dot Pencil Dress, £185, Kate Fearnley Trixie Pencil Dress, £180, The Pretty Dress Company Black Leopard Pencil Dress, £95. Unless you've been hiding under a rock you'll know all about the revival of the wiggle dress. And a classic wiggle dress, worthy of Mad Men's Joan, works best in a midi length. This curve-enhancing dress style will nip and tuck you in all the right places and because it finishes below the knee will give the illusion of a hourglass shape and slimmer, longer legs. A definite favourite with the boys! SECRETARY SEXY MIDIS Left to right: The Pretty Dress Company Royal Blue Vermont Dress, Was £101, Now £55, Lagom Petra Dress, £120, The Pretty Dress Company Charlotte Dress in Mustard, £95. The midi dress is the most office-appropriate dress around.

If your office is a little too strict for a custard hue then Lagom's Petra dress is ladylike chic at it's very best.
