Return of the underwire

The return to traditional lingerie influences is a natural evolution of the bra-as-a-top trend from spring 2017. Designers played with structured, almost corset-like bra shapes on dresses and beyond.
Seen at: Brock Collection, Chromat, Cushnie et Ochs and Helmut Lang.
Tied up

This is more styling trick than trend. Designers tied tops of identical colours and styles for a doubled-up look.
Seen at: Jason Wu, Creatures of Comfort, Hellessy and Michael Kors Collection
Springtime knits

From cardigans to deep-V sweaters and loose open weaves, knits in light pastel colours will be everywhere come spring.
Seen at: Coach, Marc Jacobs, Michael Kors Collection and Prabal Gurung
Athleisure goes sheer

At this point, we know athleisure is here to stay. The difference for spring 2018? It's now see-through.
Seen at: Custo Barcelona, Marc Jacobs, Jeremy Scott and Hugo
Safari

This perennial trend returns with a relaxed attitude and utilitarian vibe.
Seen at: Paul Smith, Gabriela Hearst, Badgley Mischka and Vivienne Tam
Rouching

Gathered detailing was everywhere—from cool-kid athleisure at Public School to ladylike maxi dresses at Tory Burch.
Seen at: Jason Wu, Kenzo, Public School and Tory Burch
Suiting 2.0

Designers' love affair with remixed suiting carried over from the fall shows. Now that the reworked shirting trend that dominated runways for several seasons is (finally) on the decline, cut-up and rearranged suits are entering the spotlight.
Seen at: Alexander Wang, Dion Lee, Jason Wu and Tibi
Raspberry

Millennial pinks older, bolder sister is here.
Seen at: Zero + Maria Cornejo, Christian Siriano, Simon Miller and Tom Ford
Dresses and pants

Whether a true dress or just an extra-long billowy top, this layering idea is still going strong.
Seen at: Alexander Wang, Hellessy, Brandon Maxwell and Sachin e Babi.
Lace-up details

The corset trend from the previous year's spring shows has evolved. Now, laced-up details are appearing on all sorts of clothes.
Seen at: Monse, Jeremy Scott, Self-Portrait and Maryam Nassir Zadeh
Fringe detailing

Fringe is back! Whether you go full-on Calvin Klein pom-pom or grungy à la Alexander Wang is up to you.
Seen at: Alexander Wang, Vivienne Tam, Calvin Klein and DVF
Foil

Baked-potato chic.
Seen at: Baja East, Tom Ford, R13 and Sies Marjan
Shiny plastic

Despite their slick appearance, spring 2018’s take on the plastic trend (which also popped up on the fall runways this year) feels soft and approachable.
Seen at: Calvin Klein, Dion Lee, Tibi and Fenty Puma
Heavy Metal

With their new takes on the ever-popular metallic trend, designers gave us chainmail, high-shine sequins and armour-like textures.
Seen at: Alexander Wang, Naeem Khan, Sally Lapointe and The Row
