TORONTO - Rachel Sin tapped into her architectural background with structure and clean lines among the definitive markers in her retro glam collection showcased at World MasterCard Fashion Week on Thursday.

Incorporating coral, blue, beige and black in her rich colour palette, the Toronto-based designer drew inspiration from shapes from the 1950s with ever-popular peplum tops and skirts for her spring-summer range.

Tailored blazers with contrasting lapels and colour-blocked skirts with exposed zippers gave an edge to polished suited separates, while delicate lace was featured as a peek-a-boo accent on the side panels of leggings and used full-scale on tops paired with blazers or worn alone.

Dress offerings included the sweet and more casual scoop-back and high-low tank dresses and ultrafeminine cocktail numbers with ruching and draped detailing.
