MARCH COLLECTION 2026
The theme of this summer’s collection is Hippie.
Easy, unforced silhouettes with a relaxed spirit—touched with just a hint of elegance. We invite you into 45R’s world of love and peace.
In March, it begins with “Indigo de Hippie.” Light-ounce denim, perfect for spring and summer, comes together in full bloom.
And as cherry blossom season arrives,
a gentle touch of pink joins the lineup,
adding softness to the indigo days.
