Last Night's Look: Love It or Leave It

01 of 44

HEIDI KLUM

Nothing to see here, just a basic black – oh wait, did you notice the two circular cutouts on her blazer to accommodate the tie at the waist? wears the Roberto Cavalli tux with a twist to the UNICEF Children’s Champion Awards in Boston.

02 of 44

MADONNA

Black lace gloves, a cross pendant, a bustier-style dress that flaunts plenty of cleavage, old school glam waves, crazy-toned biceps and badass lace-up heels. Yep, this must be a photo of Madonna. The singer wears the all-black ensemble to the Keep a Child Alive Ball in N.Y.C.

03 of 44

ALLISON WILLIAMS

Sure, the Girls star is wearing a busy paisley-and-ikat printed Giambattista Valli dress, but we’re focusing on the fact that she’s potentially donning -style nude hose. She is at a press event for Peter Pan LIVE! in N.Y.C., so maybe she’s inspired by the tights-wearing character she plays?

04 of 44

NAYA RIVERA

The actress is an inch away from not being able to wear undergarments with her slit-up-to-there slinky black gown, which she pairs with strappy heels and tousled hair at the UNICEF Masquerade Ball in L.A.

05 of 44

DIANNA AGRON

Also at the UNICEF Ball and also wearing a sexy black dress and strappy heels, Naya’s former Glee co-star styles her plunging peplum-accented midi with super-smoky eyes and a voluminous do in L.A.

06 of 44

JULIA LOUIS-DREYFUS

Looking elegant and chic as always, the actress selects a black gown with an on-trend lace neckline and long sleeves for the BAFTA Los Angeles Jaguar Britannia Awards in Beverly Hills.

07 of 44

JENNIFER CONNELLY

This is one look we could never replicate no matter how hard we tried. The actress wears a maroon and navy striped leather jacket over a white mini and styles the unique Louis Vuitton ensemble with black patent leather ankle boots at the Artwalk event in N.Y.C.

08 of 44

NIKKI REED

When attending a masquerade ball, it’s not just about what you wear over your eyes that counts, as the actress demonstrates in a graphic-print mini dress and cool black coat at the UNICEF Masquerade Ball in L.A.

09 of 44

RIHANNA

We didn’t think the could find a look any more scandalous than her infamous naked CFDA dress, but in this Tom Ford gown she wears to the amfAR Gala in Hollywood, she might have just one-upped herself

10 of 44

GWYNETH PALTROW

Not everyone at amfAR feels the need to bare everything. takes the tailored-chic route in a menswear-inspired Tom Ford suit (with a flash of skin at the back – she is still Gwyneth, after all!).

11 of 44

MILEY CYRUS

and have two things in common at the amfAR gala: both are wearing Tom Ford’s spring line and both probably needed several rolls of fashion tape to get ready.

12 of 44

TAYLOR SWIFT

In an edgy (for her, anyway) ensemble – a dark striped turtleneck, sparkly metallic skirt (both Marco de Vincenzo) and T-strap Jerome C. Rousseau pumps – visits SiriusXM in N.Y.C.

13 of 44

JESSICA CHASTAIN

For the London premiere of Interstellar the actress dazzles in a coral-pink Saint Laurent gown. Thanks to the gown’s sparkling asymmetrical shoulder strap, star-shaped Chanel diamond earrings are all the jewelry she needs to shine. (And she’s not the only celeb who’s gone galactic for this premiere – remember Anne Hathaway’s hand piece?)

14 of 44

LEA MICHELE

If she were anywhere other than the amfAR gala, deep V-neck, sequin-covered , sheer-paneled Versace dress would seem super-sexy. But compared to some of other stars in attendance (ahem, ) Lea’s look is downright tame.

15 of 44

KALEY CUOCO

The actress gets honored with a star on Hollywood’s Walk of Fame in a ladylike hot pink collared top tucked into a matching high-waisted skirt (both Monique Lhuillier) worn with pointy nude pumps.

16 of 44

JANUARY JONES

Perhaps January saw the “be practically nude” dress code for the amfAR gala and decided to wear the color nude instead? She sports a shimmering, flesh-toned Tom Ford sheath with those celeb-loved Stuart Weitzman sandals.

17 of 44

CAMILA ALVES

To support her at the Interstellar premiere in London, she flaunts a super feminine blush-colored Georges Hobeika jumpsuit that comes with a matching cape. Both her satin clutch and mesh pumps are Christian Louboutin.

18 of 44

IRELAND BALDWIN

If this outfit leaves you with a lot of questions, the model’s location should clear up a few things right off the bat: she’s at Hello Kitty Con in L.A. But the flowered headband, overdone makeup and emoji bag? Those we don’t have an explanation for.

19 of 44

ANNE HATHAWAY

We’re sensing a “night sky” theme for Interstellar premieres so far – first the star-accented navy gown she wore in L.A., and now this dazzling crystal-embellished Wes Gordon sheath worn with midnight pumps and a sleek bob to the film’s London kickoff.

20 of 44

KATE HUDSON

positively radiant in a coral lace Temperley London dress – and matching Christian Louboutin pumps to boot – plus a textured tan Brian Atwood clutch at the IWMF Courage in Journalism Awards in Beverly Hills.

21 of 44

OLIVIA WILDE

Also at the at the Courage in Journalism Awards, new mom steps out in a strapless Roksanda dress with a bold waistline ruffle, balancing the structural look with sleek Stuart Weitzman sandals.

22 of 44

RASHIDA JONES

Rashida attends the IWMF Courage in Journalism Awards in Beverly Hills wearing a black dress with a bold lace bodice, then kicks up the look further by adding Jimmy Choo pumps with embellished straps plus a vintage-y Kotur clutch with tassel detail.

23 of 44

KATE MOSS

The makes a statement like she alone can do: donning a polka-dot jacket and skirt topped off with a feather shawl and serpentine clutch for a screening of A String of Naked Lightbulbs in London.

24 of 44

BROOKE SHIELDS

Looking fabulous at 49, flaunts a hint of skin in a sleeveless, deep V-neck white gown with metallic embellishment, then tops it all off with fur at the Elton John AIDS Foundation’s “An Enduring Vision” gala in N.Y.C.

25 of 44

CINDY CRAWFORD

The supermodel shows off her curves in a figure-hugging blue dress with ruched sleeves and caged heels at the Michigan Avenue Magazine party in Chicago.

26 of 44

ALESSANDRA AMBROSIO

Alessandra upgrades the sheer panel game, sporting a bold pattern on the see-through sections of her asymmetrical Anthony Vaccarello x Versus Versace dress at the Rimowa store opening in N.Y.C.

27 of 44

JORDANA BREWSTER

Jordana puts her spin on suiting (and ditches her shirt in the process) in an ivory jacket and shorts, accessorized with glitzy heels and a clutch, at a Dsquared2 event in L.A.

28 of 44

FELICITY JONES

For the L.A. premiere of her film, The Theory of Everything Felicity sweetens up the red carpet in a pastel rose Dior dress with an elongated bodice and flared, pleated and pocketed floor-length skirt.

29 of 44

AMY POEHLER

The comedian chooses a classic look for her appearance at a 92Y Talks event in N.Y.C.: a navy, V-neck wrap dress, pointy pumps and minimal jewelry.

30 of 44

HEATHER GRAHAM

The actress picks a sculptural black satin crop top and an asymmetrical skirt with a sheer side panel for the premiere of Horns in N.Y.C.

31 of 44

JUNO TEMPLE

The star seems to have slicked back her bangs for the premiere of Horn in N.Y.C., but her Balmain structured tuxedo mini and gold Edie Parker clutch are the real head-turning elements of the ensemble.

32 of 44

SARAH PAULSON

For an appearance on SiriusXM Radio in N.Y.C., Sarah opts for a neutral-colored furry jacket that we’re thinking will elicit a not-so-neutral response from PEOPLE readers.

33 of 44

SNOOKI

The reality star’s laid-back look at the SiriusXM Radio studios in N.Y.C. makes us think she’s auditioning for our Love Her Outfit gallery with an oversize blazer, ripped skinnies and sleek heels.

34 of 44

ZOSIA MAMET

It’s menswear in a mini! The Girls actress picks a modernized ’80s power suit for the premiere of Olive Kitteridge in N.Y.C.

35 of 44

RIHANNA

The risk-taking flaunts her envy-inducing abs in a teeny pearl-embellished crop top worn under a white-trimmed top and skirt (all by Adam Selman) for the Rogue Man by Rihanna fragrance launch in Atlanta.

36 of 44

ANNE HATHAWAY

It makes sense that the would look out of this world for the Hollywood premiere of Interstellar. She stuns in a hot-off-the-runway Richard Nicoll gown, then adds star-embellished jewels (see what she did there?) by her husband’s jewelry line, James Banks Designs.

37 of 44

KIM KARDASHIAN

At her Tao-based Las Vegas birthday celebration, proves that the only thing that’s changing about her is her age, wearing an Alexandre Vauthier Couture dress that’s ultra-revealing in the front and back. (P.S. We still haven’t received word on whether she liked the birthday gifts we picked out!)

38 of 44

JESSICA CHASTAIN

This custom long-sleeved Givenchy Haute Couture gown that Jessica wears to the Interstellar premiere looks tame from the front, but the rear view reveals a super-sexy scooped back and leg-revealing lace panel. Equally as bold and gorgeous: her jade-and-diamond Fred Leighton earrings.

39 of 44

GWEN STEFANI

For the CBS Radio We Can Survive concert in Hollywood, does her rocker-chic thing in head-to-toe black – literally! Even her mani and a section of her hair are painted the deep, dark shade.

40 of 44

SARAH HYLAND

Sarah’s purple lip, messy topknot and iridescent palettes are totally futuristic, but the cut of the blouse and pants (both DKNY Resort) could have come off an episode of The Golden Girls. Only you can decide if the star’s look (at a Samsung event in L.A.) strikes the perfect balance between the two.

41 of 44

IGGY AZALEA

The new face of Forever 21 may be an international rap star on the red carpet at the “We Can Survive” event in L.A., but we’re kinda thinking her effortlessly cool outfit – a statement tee, black skinnies and a wash of violet shadow – would look just as good at a brunch this weekend.

42 of 44

ANNASOPHIA ROBB

The Carrie Diaries may be over, but we still see a hint of Carrie Bradshaw’s inspiration in AnnaSophia’s strapless trapeze dress, worn with a jeweled Corto Moltedo cluch, mismatched earrings by Renee Sheppard and Pearl Collective and a shimmery headband by Veronika Borchers for Pearl Collective.

43 of 44

JORDANA BREWSTER

The actress goes totally ladylike in a mint pleated dress, gray accessories (including Pierre Hardy heels) and a soft updo at the No Kid Hungry fundraising dinner in Beverly Hills.

44 of 44

RASHIDA JONES

Flirty ankle-strap pumps, a chic Loeffler Randall clutch and a hot pink lip are the only accessories fun enough to top off Rashida’s Thakoon feather-print number, worn to a dinner honoring the designer in Beverly Hills.
