For many of us, the idea of going into business with a sibling might seem daunting, but for Rosanna and Christie Wollenberg, the creative forces behind the jewellery label Otiumberg , their close sisterly bond became the driving force behind the creation of one of Britain’s most coveted BCORP accessories brands. Their brand ethos, "timeless and refined," is a perfect reflection of their shared style sensibilities. Rosanna names Phoebe Philo as one of her style icons, while Christie draws inspiration from the Olsen twins and their cult-favourite 'quiet luxury' label, The Row.

“We’ve always designed what we would wear ourselves, and the same goes for our wardrobes,” Rosanna tells us. The sisters are the embodiment of the saying, "if it isn’t broken, don’t fix it," in their approach to fashion. Rosanna has "a few waistcoats in rotation for the week," while Christie is never without her signature "trainers, always.

" As jewellery designers whose creations have graced the likes of Emilia Clarke , Iris Law , and Emma Appleton, we couldn’t help but ask the stylish duo for their top accessory styling tips. From stacking cuff earrings to personalised bracelets, they reveal their must-know fashion secrets, offering a glimpse into their chic, insider world.
