Sometimes, just sometimes, high street stores get it so right that they'd fool you into thinking a piece is designer.

H&M is one of those stores - it does great affordable basics as well as some stand-out items that become cult buys each season. With summer sales wrapping up and the fashion world already turning its focus to autumn/ winter style, there's one dress by H&M that's really caught our eye for the season ahead. This austere button-up shirt dress looks every bit the high-end piece with its puff sleeves and contrast stitching, so much so that we couldn't actually believe it's from H&M and costs €69.99. They've styled it in an edgy, editorial way with matching culottes and a beret but our own Rosie Connolly has just proven that it can be made a lot more wearable. The Dublin-based blogger donned the dress as she headed to a beauty event in London yesterday. Rosie kept the look super casual, unbuttoning the collar and pairing it with white Adidas runners, a cross-body Prada bag and loosely curled hair. We also spotted the same dress at Paris Fashion Week last month. Across Daphne Patakia was seen wearing it as she attended a Fashion Week event in the French capital.
