Whenever I'm in Mango, Zara, or H&M, I just feel like I am home (both in the store and online). Each one is relatively similar, and I know my favourite sections—where I'll find more going-out pieces, where they place their newest items, where the more discounted pieces are hiding, and so on. This, if you ask me, makes me an expert when it comes to the power three. After checking my wardrobe and realising that I've acquired quite the summer collection solely from the retailers this season, I decided it was time to do a haul of all the glorious summer pieces they're unveiling on their sites daily. So if under-£100, extremely chic, on-trend things are what you're after, please allow me to introduce you to these 26 add-to-cart-worthy items.
