This quilted jacket in deep sea is particularly flattering for Soft Summer and Cool Summer colour seasons. The muted blue-green shade combines coolness with softness, creating the kind of refined colour that Summer palettes naturally suit. Soft Summer benefits from the gentle, low-contrast quality of the hue, while Cool Summer wears the cool undertones beautifully. Unlike brighter teals or stronger greens, deep sea has a subtle sophistication that makes it exceptionally versatile, pairing effortlessly with other Summer neutrals and accent colours. For anyone building a colour analysis-led wardrobe, this is the kind of outerwear piece that offers both practicality and palette harmony, bringing softness and depth to everyday outfits.
