That sounds like a stylish and versatile dress! The bright red and mustard yellow colour combination is sure to turn heads. Pairing it with coloured sunglasses is a great way to add a pop of colour to the outfit. The side slits will also add a touch of sophistication to the dress while allowing for ease of movement. As mentioned, sheath dresses are very versatile and can be styled in many ways. A light-coloured swing jacket or cardigan would be a great addition to wear over the dress for a smart daytime or business casual look. You could also layer a top over the dress to transform it into a pencil skirt, adding even more versatility to your wardrobe.
