Marks and Spencer fans are snapping up a gorgeous boho-style autumn dress that has been designed to cinch in the waist and will flatter bigger arms. As well as an eye-catching ombre design that will turn heads no matter what the occasion, the dress, which comes in two colourways, has been designed to suit all body types, shapes and sizes.

Marks and Spencer's £49.50 Ombre Tie Waist Pleated Midi Waisted Dress has been described as 'an elegant choice for weddings and other formal occasions', but can also be worn for work, nights out, Christmas parties and more relaxed settings with a leather or bomber jacket and boots.
