What to Expect on the Sixth Day of Paris Fashion Week

PARIS — Start gargling saltwater, all ye who were out late at Givenchy last night, and empty out your leather purse into a cloth tote or something, because at 10 a.m. Stella McCartney, the groovy Beatle daughter and mum of four, is showing her winter collection with vegan shoes and probably some faux furs at the Opéra Garnier.

Then at lunchtime, get out the real fur and join a flight of Italian sister-socialites (the Brandolinis, the Missonis and maybe Lee Radziwill) at the Grand Palais for the show of Giambattista Valli, the purveyor of Lena Dunham’s pink ombre confection at the last Emmys, among many other delightfully foofy creations.

O.K., where’s that leather purse again? Sling it over your shoulder and trit-trot over to the headquarters of La Garde Républicaine, where at 4:30 p.m. Hermès will hold its first show under the creative direction of Nadège Vanhee-Cybulski, replacing Christophe Lemaire, who is now attending to his own label.

Finalement, let there be Saint Laurent, if not light, at a covered market in the Third Arrondissement where chic-seeking missiles will touch down at 8 p.m. The house’s current designer, Hedi Slimane, has sent out a book of mimeographed sketches and collages by the artist Jim Shaw titled “He Drew the Dirtiest Thing He Could Think Of” — reminding this reader (in theme, at least) of Yves Saint Laurent’s perverse graphic novel, “La Vilaine Lulu.”
