Leaving his namesake label to defend his creative autonomy could have been a career-ending move for Alessandro Dell'Acqua. But since launching No. 21 in 2010, he has been welcomed with nothing but resounding praise for the label’s unique ability to straddle the worlds of demi-couture design and everyday ease. For Spring 2016, No. 21’s distinct brand of androgyny proves an ideal match for the ’90s trend that’s gaining serious traction this season. Dell'Acqua reminisced on the decade with floral print pajama-suits, T-shirts layered over delicately frayed chiffon slip dresses, and tank tops and skirts that were pieced together from supple strands of leather. The intermingling of soft textures and mannish, oversized silhouettes perfectly embodied the mix of grunge and glamour that defined the decade. The perfect finishing touch? Socks worn with sandals.
