The cutout craze knows no limits — including age. Youngster Kiernan Shipka and the stoic Katie Holmes both repped the popular trend on their respective red carpets this week, while Jessica Chastain went the opposite route, getting lost in head-to-toe Oscar de la Renta.

Kiernan Shipka

The young “Mad Men” star shines in a Delpozo frock with an age-appropriate flower detail at the Tribute to “Mad Men, Part Two” event in LA.

Katie Holmes

The “Woman In Gold” actress is pink perfection in a Zac Posen frock for the film’s NYC premiere at the Museum of Modern Art.

Caitriona Balfe

The Irish actress celebrates her plum role in the Starz hit TV series “Outlander” in a jewel-tone Roland Mouret gown for the show’s mid-season screening at the Ziegfeld Theatre in Midtown.

Kate Mara

The former “House of Cards” actress is fashion-forward in a Dior dress with intricate cutout details as the fashion house presented the 2015 Mid-Winter Gala in San Francisco.

Lily-Rose Melody Depp

The 15-year-old daughter of Johnny Depp and Vanessa Paradis steals the spotlight at the Chanel runway show in NYC, wearing a matching skirt and crop top from the iconic brand.

Jessica Chastain

It’s rare to see the classy redhead make an ill-advised fashion decision, but the “Interstellar” actress gets lost in this long-sleeve, high-neck, floor-length Oscar de la Renta gown at the Jameson Empire Awards in London.

Rihanna

We get it, RiRi — you like to break all the fashion rules. But a graffiti’d trench coat over booty shorts and a bra (and don’t forget the bucket hat!) is not a style statement, it’s just lazy.

Jennifer Hudson

Though her Herve Leger by Max Azria dress certainly channels a Mardi Gras-meets-“Cabaret” vibe (not a good thing), it’s Hudson’s worrisome bowl cut at the iHeartRadio Music Awards in LA that truly makes this look a disaster.

Michelle Rodriguez

The “Furious 7” actress’ Vivienne Westwood column dress looks like something we’d see hanging on our grandmother’s windows — and clashes with Rodriguez’s beach-inspired tresses.
