Celebrities have teams of stylists who work on their wardrobes, whether that’s weeks of negotiations to secure a red-carpet gown or borrowing looks straight from the runway for interviews and public appearances. Of course, personal stylists still often play a role in off-duty wardrobes too, however it’s not all luxury samples and fine jewellery.

There are several affordable brands that you’ll see celebrities wearing day in, day out – and certain stars are known for always having a curated high-low mix. Sienna Miller and Katie Holmes are two that come to mind, as they are often spotted wearing casual staples by the likes of Mango, Sézane and Cos. On the jewellery front, Missoma and Mejuri are cult favourites among the It-crowd, both of which specialise in versatile everyday pieces.

The best affordable brands to consider adding to cart are those that provide a balance of comfort and style. Most importantly, to ensure maximum wear, an affordable product must fit seamlessly into your wardrobe – in short, only invest in something you can see yourself wearing beyond a single season.

Scroll on for a lowdown on these brands – and the best pieces to shop now.

Cos has long specialised in minimalist staples – but in recent years, it’s broadened its offering to include pops of colour and patterns. Celebrities and editors alike have fallen for the appeal of the brand’s swaddling outerwear and selection of everyday accessories.

LA-based brand Reformation has a long list of loyal celebrity fans who rely on the brand for its strong denim edit and easy-to-wear dresses, which are ideal for wedding guest season – and beyond.

Parisian brand Sézane has garnered a cult following, with queues often snaking outside of its shops (which are called the apartments) in Paris and London. It is loved for creating elegant wardrobe staples, such as wrap coats, denim jackets and knitwear, which you’ll see the likes of Selena Gomez and Sienna Miller wearing.

Almost every day the fashion desk spots another celebrity wearing Mango. Known for its simple basics, minimalist outerwear and tailoring, the high-street brand has become a mainstay in stars’ wardrobes.

Celebrities often borrow fine jewellery for red carpet appearances, however Missoma is also a popular choice for its selection of gold hoop earrings, chain necklaces and signet rings – which are worthy of wear for both day and night.

Whether you have a penchant for minimalist designs or bold, statement pieces, Mejuri offers jewellery for every occasion. The brand’s simpler pieces – like its delicate stacker ring – are perfect for everyday use, while the croissant hoops or pearl drop earrings will flourish an evening look. It has a long list of celebrity wearers, including Meghan Markle, Margo Robbie, Taylor Swift and Selena Gomez.
