Earlier this month I talked about the idea of guilt free designer shopping (if you missed it and want to catch up click here) with a view to heeding Dame Vivienne Westwood's ""buy less, choose well, and make it last" advice a little more scrupulously than I have done in the past. Having worked in retail, I've seen my fair share of compulsive shopping - hell, I've even done the occasional bit of it myself, and I know it can be hard to break those bad shopping habits. One of the best pieces of advice I can give you is shop for yourself and only take pieces you love from a trend. For example, if pastel jeans aren't your thing, then why did you just spend the weekend trying to find a pair you'll only ever wear (uncomfortably) once? If you hate the tribal look, then why are you trying to impress with an expensive Navajo inspired jacket that will sit in the back of your wardrobe gathering dust?

The best way to shop for designer pieces in my opinion is to choose something timeless. Whether it's printed or plain, choose an item you can wear a hundred ways, that you feel yourself in, and that you'll wear again and again, to the office, to the shops or on a date. Beginning life in 1856 and holding two Royal Warrants, Burberry Brit is steeped in history, yet continues to be at the forefront of fashion today. Exuding the iconic British brands effortlessly cool style, this elegantly tailored shirtdress from Burberry Brit is the perfect item for any fashion savvy shopper. For an everyday look, channel uber cool Brit girl, Alexa Chung, and team with brogues, skinny belt and a parka. Going out for dinner? Embrace the Duchess of Cambridge Kate Middleton and pair with nude tights, court shoes and a clutch bag.

Burberry Brit cotton-voile shirt dress £295 Net-A-Porter

This knee length number would look amazing paired with a trench coat on a rainy day - roll the sleeves and tie the belt in a knot at the waist for a bang on trend look. If you're heading out for dinner on a summery evening, rock a statement colour or printed blazer and keep accessories to a minimum. The shirt dress is a key piece for any girls wardrobe, and makes for an exceptionally cool work outfit when paired with a tailored jacket too.

Tights are the easiest way to change the whole tone of this dress, or any other for that matter. Play it safe and chic with nude, black, or add a pop of colour with a marl grey or burgundy pair. If you're feeling daring, why not go for patterned tights and really stand out from the crowd?

Shoes glorious shoes! Anything goes with this baby, although wedges, gladiator sandals and brogues in particular work best. Do your best Kate Middleton impression with a pair of nude court shoes or colourful wedges, rock it like Alexa Chung in a pair of brogues, or wear it on the beach with a pair of super strappy sandals for an Olsen sister vibe.
