Perfecting 18-hour style is admittedly a tricky task but one that can put the ease into prepping for back-to-back plans when done well. We've put together a Fashion Notes guide on how to style day to night outfits, focussing on three of our favourite new-season pieces and capturing key AW15 trends. NB: Forward-planning is essential.

The perfect wrap dress is a wardrobe staple with timeless appeal, so for flawless 18-hour style that requires minimal effort, look to the season’s favourite Perdy black dress. Long sleeves render it refined enough for day and the layered wrap-around front adds that little something extra to secure its evening status. Switch a leather tote and flats in the day for graphic cut-out heels and a decorative box bag after dark. The luggage-inspired design and gold-tone metal detailing of the Efren will lend the all-black palette a high-shine edge without stealing the focus.

For an on-trend look that works around the clock, the burgundy Iva pencil skirt is a striking option. Cut from structured neoprene, it will add subtle texture to your outfit without compromising the style's recognised clean-cut lines. The trick here is styling it appropriately for day. We suggest a slouchy knit, bare legs and block-heel ankle boots for a relaxed yet on-point look that strikes the balance between smart and cool. To switch it up for evening, try a decorative black top and cut-out heels. Crochet or lace fabrications offer a modern contrast of texture and a metallic clutch and a bold nail colour will bring an element of fun to the look.

Part of the Reiss Premium collection and cut from the softest pure silk, the navy Fauna top is a luxe investment piece. The simple shape and minimal detailing make it especially versatile so it’s the perfect day to night piece. For day, style it with anything from jeans at the weekend to tailored trousers in the office, or wear it with a tailored short suit for a chic yet smart alternative. Come evening, we suggest pairing it with leather trousers – the clash of texture will emphasise its premium status. Simple accessories such as a statement metal cuff and leg-lengthening heels complete the look perfectly.
