Armed with a battalion of celebrity ambassadors, L'Oréal took over the historic Paris Mint building to stage a Paris Fashion Week extravaganza. Offerings from Elie Saab, who went 1970s, and Vivienne Westwood, who stylishly towed a line between ethnic and punk, made for a frenetic pace of shows on Saturday.

Here are some highlights of the day's Spring-Summer 2020 ready-to-wear displays:

L'Oréal's celebrated female empowerment at its third fashion show, which featured actresses Helen Mirren and Eva Longoria giving turns as models and was broadcast to over 40 countries.

Whatever the styles lacked in unity - they harked from diverse design houses that included AMI, Balmain, Dries Van Noten, Elie Saab and Giambattista Valli - they made up in razzmatazz.

ELIE SAAB CHANNELS CIRCLES, 70s

The circles, at times, appeared controlled, such as the tiny perforated eyelets on a sporty white mini dress with long tassels.

The collection indicated that Saab, who found fame with va-va-voom cinched-waist looks, seems to be moving out of his comfort zone.

The mood seemed to suit Kronthaler: it resulted in a spring collection that moved the house of Westwood in a welcome, more focused direction.

A checkered pattern on loose or gathered skirts cut a fine contrast with a metallic blue double-breasted jacket that had the gigantic round shoulders and glimmer of the 1980s.

L'Oréal's celebrated female empowerment at its third fashion show, which featured actresses Helen Mirren and Eva Longoria giving turns as models and was broadcast to over 40 countries.

The French cosmetic giant's display still was less ambitious than last year's edition, which took place on the Seine River, or the one staged in the center of the Champs-Elysees that literally stopped traffic in 2017.

Nonetheless, Mirren, Longoria and Dutch model and former Victoria's Secret Angel Doutzen Kroes energized spectators at the evening show, joining Cuban-American singer Camila Cabello, American model-actress Amber Heard and other new L'Oréal models to show a collection of carefully crafted looks.

Whatever the styles lacked in unity - they harked from diverse design houses that included AMI, Balmain, Dries Van Noten, Elie Saab and Giambattista Valli - they made up in razzmatazz.

A strong-shouldered tuxedo mixed with a 70s jabot collar shirt on Mirren, styled with her hair slicked back, contrasted with more feminine styles, such as a trapeze-shaped, shoulder-less coral gown or the dazzling pearl-hued ruched number Longoria wore.

The L'Oréal brand's cachet in makeup could not go unnoticed. Kroes and other models were made to look nymph-like, thanks to makeup director Val Garland and hair baron Stephane Lancien.

ELIE SAAB CHANNELS CIRCLES, 70s

A vivid red screen flanked the Elie Saab runway inside the grounds of a Paris institution, the Michelin 3-star restaurant Alleno Paris at the Pavillon Ledoyen.

The Lebanese designer got decorative and turned the style-dial firmly back to the 1970s. Small circles were a key theme.

The circles, at times, appeared controlled, such as the tiny perforated eyelets on a sporty white mini dress with long tassels.

Later, the theme had a boho vibe: a petite sunflower print adorned a floor-length black gown worn by a model styled with her hair in an Afro.

A silk gown in rich electric blue had a looser-than-normal silhouette and a waist that was tight without being cinched. Thick banding led the eye down to a sumptuous full skirt that gently grazed the floor.

The collection indicated that Saab, who found fame with va-va-voom cinched-waist looks, seems to be moving out of his comfort zone.

And it's paying dividends.

WESTWOOD'S HIGH PUNK PRIESTESS

Designer Andreas Kronthaler merged his signature urban punk with fresh tribal styles for the Vivienne Westwood show set amid dark brooding light.

The mood seemed to suit Kronthaler: it resulted in a spring collection that moved the house of Westwood in a welcome, more focused direction.

A gargantuan pointed hat - part high priestess, part Marie Antoinette - was paired with a bathing suit bodice, a great detail that set the tone for a display of quirky contrasts.

Ethnic jewelry abounded along with knee-high soccer socks. A pale silver headdress billowed fabric ribbons that nestled eccentrically on a pair of loose culottes.
