Leather trousers top the list of women's most regrettable fashion buys Shell suits, velour tracksuits and leather trousers top the list of women's most embarrassing fashion purchases, according to a new study. It's a sad fact of life, but unless you've borrowed Rosie Huntington-Whiteley's never-ending, toned legs for the day, those leather trousers - playfully winking at you from the shop rail - should be left well alone. A lesson that many a woman has come to discover all too late, according to a new survey by Lambrini. The sparkling perry supplier to the women of the nation who 'just wanna have fun' coaxed the admission from 920 out of 2000 women, making leather trousers the item with the biggest regret factor at 46 per cent - despite them being one of the biggest trends of the season.

Team Telegraph can't recall anyone aside from fictional character Vicky Pollard wearing a suit of the shell variety this side of 1999, so we cant quite fathom when these lest-we-forget purchases were made, however X Factor judge Tulisa Contostavlos (AKA Britain's worst dressed woman) has stolen Paris Hilton's crown as Velour Tracksuit Wearer Of The Decade; we point the finger firmly at her camel-toed door on this one. IN PICTURES: 20 things women hate about men's wardrobes Other 'what was I thinking' purchases to make the list include fluorescent outfits at number four (only clubbers under the age of 25 can subscribe to neon); sheer tops in fifth position (a favourite of flesh-flaunting Nancy Dell'Olio); bum bags at number six (redeemed only by Rihanna) and crop tops at number seven. Puffa jackets, Crocs, thigh-high boots, hot pants, clogs, miniskirts, flared trousers and ponchos also form part of the top fifteen - but let's rename that the 'feared fifteen' after this study. IN PICTURES: Ten things men hate about women's wardrobe The Daily Mail report how many women found leather trousers "tacky" once they got them home, and clothes appearing "cheap" catapulted them to the top of their disaster directory.
