Five workwear essentials
By Clemmie Fieldsend
Fabulous Fashion Editor Clemmie Fieldsend shared the five workwear essentials everyone should have.
1. WHITE SHIRT
A good white shirt is so versatile. Great for wearing on their own or layering underneath knits and transforming plain jumpers by adding cuff and collar detail, as well as wearing open over plain tops.
2. WIDE LEG TROUSERS
They've become a wardrobe staple over recent years as they are comfortable, flattering and will elevate your workwear. Look out for styles with pleating or darting.
3. PRACTICAL TOTE
for a day at work or on your commute you'll need all your essentials with you, cram them all into a sleek and stylish tote bag in a neutral colour like black, brown or beige so it can be used with all of your outfits.
4. TAILORED BLAZER
Even if worn with torn jeans a tailored blazer will instantly make you look polished and smart for work. Black will be the most useful and look for silhouettes with structure.
5. SIMPLE LOAFER
Whether you like delicate or chunky, a flat and comfortable shoe is essential for everyday use and can look just as dressy as a heel.
