While leading ladies like Marilyn Monroe may praised for their memorable on-screen fashion, let us not forget their stylish best friends and supporting actresses.
From Iona in Pretty in Pink to the equally pink Frenchy in Grease, all hail the stylish sidekick!

Geena Davis, 'Thelma and Louise'
Louise Sawyer has impeccable style. Just look at that denim jacket!
Jane Russell, 'Gentleman Prefer Blondes'
It's hard to compete on screen with Marilyn Monroe, but Jane Russell holds her own as Dorothy Shaw.
Annie Potts, 'Pretty in Pink'
Annie Potts as Iona in Pretty Pink is one of the coolest best friends in film. (And clearly was a style inspiration for Lady Gaga!)
Emma Watson, 'Harry Potter'
Hermione Granger as known more for her brains than her fashion sense, but we love her sensible style.
Didi Conn, 'Grease'
Although not as cool a Rizzo or as sultry as Marty, Frenchy had a colourful style all her own.
Jennifer Coolidge, 'Legally Blonde'
A typical "quirky best friend' in a romantic comedy, Paulette's style may not be as, erm, pink as Elle's, but she certainly stands out.
Thora Birch, 'Now & Then'
Thora Birch as Tina "Teeny" Tercell is the most glamorous of the bunch in this classic gal-pal film.
Scarlett Johansson, 'Ghost World'
Although she might not look quite as cool as Enid, Johansson's style as Rebecca Doppelmeyer is still fantastic. Theres something very Margot Tenenbaum about her.
Barbara Hershey, 'Beaches'
It must have been cold in Bette Midler's shadow, but Barbar Hershey looked fabulous as Hilary in Beaches, anyway.
Lili Taylor, 'Mystic Pizza'
Lili Taylor as Julia Roberts pal Jojo Barboza is fabulous - even if the movie isn't exactly that great...
Lizzy Caplan, 'Mean Girls'
Most of us in high school were more of a Janis Ian than a Regina George, which is why we love her so much. Lizzy Caplan, we love you!
Daryl Hannah, 'Steel Magnolias'
Annelle Dupuy Desoto loved Jesus and may have got on the other women's nerves, but damn didn't she look amazing doing it.
Madonna, Desperately Seeking Susan
Madonna is technically the supporting role in this film, and just look at her. How many of us tried desperately to recreate this look? How many hours did we all spend trying to get our hair just the right amount of messy?
Fairuza Balk, 'The Craft'
Sure, Nancy got a little crazy with things, but at least she looked cool doing it.
Drew Barrymore, 'Boys on the Side'
We love that Drew Barrymore's wardrobe as pregnant Holly reflected her own style!
Ginger Rogers, 'Stage Door'
Playing Katharine Hepburn's roommate and (eventual) friend, Ginger shines as the fabulous Jean.
Madonna, 'A League of Their Own'
Madonna as the cynical, straight-talking Mae is one of the highlights of the film - her wardrobe included. Even the way she wears her hat is cool.
Kate Hudson, 'Almost Famous'
Kate's award winning performance as Penny Lane is incredible, as is her wardrobe. From crop tops to that stunning fur coat - Penny has fantastic Band Aid style.
Rosie O'Donnell, 'Sleepless in Seattle'
From her adorable '90 perm to her brilliant blazers, we love Rosie as Meg Ryan's best friend Becky!
Dolly Parton, '9 to 5'
Dolly Parton's wardrobe as Doralee Rhodes is fabulous, and so typically Dolly. Amazing hair, as usual, Dolly.
Maya Rudolph, 'Bridesmaids'
Maya's simple elegance as Lillian in Bridesmaids is gorgeous. Her outfit here is reminiscent of something Kate Middleton might wear.
Tricia Joe, 'Baby-Sitters Club'
Tricia Joe did not disappoint as stylist Claudia Kishi of The Baby-Sitters Club. Just look at that skirt! Stylin'...
Joan Cusack, 'Working Girl'
Joan Cusack may forever be the quirky friend in films, but she always looks amazing. The height of her hair in Working Girl is stunning.
Stacey Dash, 'Clueless'
Stacey Dash's costumes as Dionne Davenport in Clueless are one-of-a-kind. Dionne wore plenty of fantastic hats in the film, including this one. (Is it a lampshade??)
Laura San Giacomo, 'Pretty Woman'
What's not to love about Laura's look as Kit De Luca?
Michelle Williams, 'Dick'
Michelle's wardrobe as Arlene Lorenzo is fantastic. Her colourful '70s style is brilliant, although her American flag outfit in the film is, admittedly, a bit much.
Cheryl Hines, 'Waitress'
From her super cute waitressing outfit to her personal style as Becky, Cheryl is sweet as pie in Waitress. (See what we did there?)
Rosario Dawson, 'Josie and the Pussycats'
Valerie Brown was a brainy bass player with a delightful, feline-inspired wardrobe - which makes her one of the coolest, most stylish friends on film, ever.
Heather Matarazzo, 'The Princess Diaries'
Mia's best friend Lily is an absolute sweetheart, and her wardrobe is, well, accidentally cool. Teddybear backpack, anyone?
Janeane Garofalo, 'Reality Bites'
Vickie is probably the most stylish person to ever work at The Gap.
