Carolina Castiglioni has found a new way to deliver the effortless chic her Plan C brand is known for. The label has carved out a niche of loyal customers with its intriguing mix of workwear, tailoring and sporty references that zhuzh up everyday dressing.

But for spring 2026 Castiglioni broke free from the urban landscape and had her Plan C tribe take some time off — be it at the seaside or in the mountains. The vacation theme magnified the laid-back elegance of Castiglioni’s clothes, making the case for covetable pieces to pack but also to wear again and again, even after returning to one’s daily routine in the city.

The lineup charmed with its heightened sense of spontaneity and naïf elements, detectable in everything from a crisp poplin dress with puffy shoulders and frill hemline to cute jewelry shaped as paddle boats or vintage toy cars.

Some key looks were shared between women and men, including relaxed suits, cool pajama sets with contrasting piping and drawstrings, and zippered nylon anoraks letting lace slipdresses or paneled Bermuda shorts peek from underneath. 

Crinkled textures and asymmetric details amplified the nonchalant vibe, as seen on gauzy frocks in buttery shades, as well as a fluid long dress rendered in vibrant red or cut from a floral-printed silk fabric with a glossy effect, which was haphazardly gathered on its upper part. 

Elsewhere, ruffles running down striped shirts or viscose sets and knits playing with transparencies infused delicacy with their pastel color combinations; padded jackets in papery textures came with matching sequined-embellished skirts; while the simple lines of a leather jacket were elevated by a flower intarsia on the back.

Those hoping to bring a Plan C souvenir back from the holidays can opt for an easy-peasy T-shirt printed with an original artwork by Castiglioni. It depicted a geometric vase with flowers, teasing the launch of the brand’s homeware collection developed with Belgian design label Serax.
