The latest edition of the Lyst Index is a clear representation of the current landscape of the fashion world. Luxury and low cost are starting to fuse in the search for garments that make a difference and maintain an aesthetic in which the classic and the so-called silent luxury have become the most desired objective of the moment.

And this quarterly ranking, in which the brands and items most popular in the industry are selected, has brought to the fore names such as Massimo Dutti and COS. The Inditex brand and the Swedish label appear alongside giants like Saint Laurent, which has taken the throne, or Miu Miu.

Focusing on COS, the Swedish brand thus gains great importance and reaffirms its leadership among a consumer who appreciates quality and design, but also values a more affordable price suitable for almost all budgets.

Its minimalist, elegant and functional style, based on timeless garments, architectural cuts and the use of sustainable materials, has made its premium proposition one of the favorites among fashion lovers. And these basics that they have already launched for spring are the best proof of it.

Knit Cardigan

Another essential basic for spring is a good knit cardigan, perfect for staying warm in those cooler moments, but also ideal to wear without a jacket when temperatures rise. We love this model made from mohair and merino wool, with a textured zigzag stitch. It stands out for its pistachio green color, its slightly cropped structured silhouette, and its front button closure. Price: 99 euros.

Blue Shirt

Among the favorites for an timeless and wearable wardrobe is a good blue shirt, and COS confirms this with this very flattering model that offers a modern take on tailoring classics. Designed in a sky tone, it is made from ultra-soft cotton and we love it for its structured and slightly masculine style, which is particularly flattering. Price: 69 euros.

Barrel Trousers

The brand has also confirmed the power and trend of barrel trousers. This leg design with a rounded silhouette is highly fashionable and invites you to join in with a wool version featuring a modern, very wearable silhouette. It also includes a buttoned hem adjustment that lets you modify the leg shape to a straighter fit, thereby making it highly versatile. Price: 129 euros.

Striped T-Shirt

Another basic we love is a good striped T-shirt, but going far beyond the classic navy-and-white sailor model. In this case, it’s a cotton option with a thoughtfully flattering cut, pairing burgundy with white. A safe hit. Price: 39 euros.

Denim Midi Dress

Another favorite of ours is this indigo denim midi dress. It features a silhouette with darts, a shaping effect, and a back patch pocket. It has no sleeves, so you can wear it when temperatures rise, but also now with a long-sleeve tee underneath. Price: 89 euros.

Checked Trench Coat

The penultimate piece is a trench coat. This type of jackets is essential for the upcoming season, and COS has launched one of the most original proposals of the moment. It is a design featuring a checkered pattern and crafted in a premium cotton fabric with a special waxed finish. Price: 199 euros.

Asymmetric Blouse

Finally, for those seeking pieces that stand out and make a difference, this asymmetric blouse stands out. A sculptural model crafted in structured cotton, with a curved silhouette that is complemented by a modern asymmetric collar and shoulder button closure. Price: 89 euros.
