When it comes to summer colours, mustard isn't one that immediately springs to mind.

We tend to live in in the chillier months but is worth adding to your wardrobe for the upcoming season too. Mustard can really pop with a tan and is a handy shade to style. It can also look a little more expensive than brighter yellows. Take this divine €18 dress from Penneys. Though it comes up almost chartreuse on camera, it's more mustard in real life. We love the button-up front and simple cap sleeves, plus the broderie anglaise pattern. This is one you'll wear everywhere all summer long; a handy throw-on-and-go piece that doesn't need much else. Also going straight in our basket for holidays is this adorable floral skirt for €16. Penneys first released a dress in this print and now this. Pair it with a biker-style jacket, white tee and ankle boots and you have the perfect look to take you from desk-to-drinks this spring and summer. And how fab would it look with a colourful camisole - like a matching pink-shade? - trainers, and a denim jacket for the weekend? Lastly, we need to get our hands on the savage €3 sunglasses that are total dupes for Celine's Traveller shades. Worn by the likes of Ashley Benson, Kim Kardashian and Sofia Richie, the glasses are the ultimate in designer style but don't come cheap. A pair will set you back a couple of hundred euro, making the Penneys version an absolute steal.
