This piece is made from a fabric blend of 60% Polyester, 20% Viscose, and 20% Cotton. The fabric is a yarn-dyed vertical stripe material with a clear texture that is crisp and breathable, carrying a subtle creased quality that deepens its retro character after washing. The blend supports the relaxed, casual aesthetic of the set while keeping it comfortable for summer wear, and the same fabric is used throughout both components of the two-piece design. The deep navy base with fine same-tone white vertical stripes creates a retro workwear feel, and the low-saturation navy suits a range of skin tones. The fabric's crisp, breathable handle makes it suitable for casual summer occasions, while the subtle creased texture reinforces the relaxed, retro aesthetic of the piece.
