Old Hollywood glamour, the Ice Spice way.

Over the weekend, the singer swapped her go-to curls for a retro hairstyle.

Spice channeled her “Princess Diana” song with pretty waves we know Lady Di would approve of.

Her bob rested right at her jawline and featured classic, glamorous waves parted to one side.

Each wave was styled in an exaggerated curl, adding to the hairstyle’s sculpted feel.

The orange creamsicle shade of her hair put a modern touch on the vintage style.

The highlight of her makeup was her glossy brown lip and sleek retro black eyeliner.

The rest of her outfit followed the orange color palette.

Like Tyla, Spice wore a vintage Versace gown from the brand’s Spring/Summer 2004 collection.

(It was as though Marilyn Monroe was put in a Y2K time machine).

She paired it with matching strappy sandals and a butterfly diamond chain.

Old Hollywood glamour, but add a little spice.

Her stamp of approval gives us an inkling that the retro trend isn’t going away anytime soon.
