Rihanna attended the Time 100 Gala earlier last month. For the occasion Rihanna wore a pink prom-style dress by Marchesa. It is refreshing to see Rihanna in such a ladylike dress when she usually chooses something much funkier.

The Tribeca Film Festival took place earlier last month with all manner of actors and actresses flying in to promote their newest work.

Michelle Williams made an appearance in an ultra feminine pleated white and yellow dress by Giambattista Valli. This is Michelle at her best.

Olivia Wilde made several appearances. She chose a sexy black Mason by Michele Mason dress teamed with chunky Brian Atwood sandals. She appeared again for the premiere of The Five Year Engagement in a patterned maxi dress by Yigal Azrouel.

Emily Blunt also attended the premiere of The Five Year Engagement. Emily chose a strapless prom dress in green and black from the pre-fall 2012 collection by Jason Wu.

Leelee Sobieski attended the opening of the Tribeca Film Festival wearing the dress that had all the fashion press sighing at the shows back in October. She wore a white ball gown shirt dress from the spring 2012 collection by Jil Sander.

Dakota Fanning also attended the opening event wearing a cute pink tulip skirted dress from the pre-fall collection by Lanvin.

Catherine Zeta Jones made an appearance alongside husband Michael Douglas. Catherine looked glamorous in silver sequinned one shoulder dress by Michael Kors.

Madonna made the step that seems to be a well-trodden ground in celeb circuits and launched her own perfume in New York last month. For the launch she chose a classic black dress by Dolce & Gabbana. This is the kind of look I like to see on Madonna – sexy without being obscene.

Scarlett Johansson has been busy this month promoting her new movie The Avengers. First up she appeared in LA for the premiere. On this occasion Scarlett chose a sleek look in a black Versace dress with on-trend peplum from the fall 2012 collection teamed with Giuseppe Zanotti strappy heels.

She later headed to London for the European premiere held at Westfield. On this occasion she went for a girlier look in a strapless red and blue dress with black rose prints by Prada. She added red Christian Louboutin pumps and a grecian style hair plat.

Last week Scarlett was awarded a coveted star on the Hollywood walk of fame. For this occasion she chose a top and pencil skirt duo from the fall 2012 collection by Preen. This kind of pencil skirt shape is a good look on Scarlett making the most of her hour-glass shape. She added a pop of colour to the monochrome ensemble with red Christian Louboutin peeptoe shoes.

Last month actress Charlize Theron attended CinemaCon in Las Vegas where she was awarded with the Distinguished Decade of Achievement award. For the event Charlize went for a sexy look in a black body-con dress with cut-out details from the fall 2012 collection by Dion Lee she teamed the dress with Giuseppe Zanotti sandals. This is a nice look on Charlize and fits in well with the more sporty looks we’ve been seeing this season.

Some of Hollywood’s most fashionable stars were out in NYC this week for the premiere of The Five Year Engagement.

The film’s leading lady Emily Blunt looked chic in a strapless embroidered black and green Jason Wu dress from the pre-fall collection. She wore matching green Alice + Olivia heels, and accessorized the dress by adding a belt, Lorraine Schwartz earrings and a Valentino clutch.

Actress Olivia Wilde was also in attendance and had a more daring look. She wore an animal print pre-fall 2012 maxi dress from Yigal Azrouël, gold earrings from Ippolita, and a gold Jimmy Choo Clutch.

Camilla Belle was also wearing Jason Wu for the premiere; she however wore a much more seductive metallic figure hugging dress. The dress has the fabulous figure flattering black panels that we have been seeing a lot of recently on the red carpet.

My favourite look of the evening was Leelee Sobieski. Leelee wore a stunning Boy. by Band of Outsiders fall 2012 black halter neck dress with a thigh high split. The stunning dress has a bandage bodice and chiffon draped skirt, she finished the sophisticated look off with slick back hair, and understated black Alaia sandals.

The annual Academy of Country Music Awards took place at the weekend at the MGM Grand hotel in Las Vegas. The star of the ceremony was Taylor Swift who won Entertainer of the Year. Taylor wowed in a white dress with cut out details from next seasons fall collection by J.Mendel. This is a more serious, sexier look for Taylor that is a vast improvement on her usually more girlier ensembles.

Nicole Kidman made an appearance at the awards to support her husband. Nicole went for a classic look in a black shift dress with sheer panel neckline detail from one of her favourite designers, L’Wren Scott.

Finally Leann Rimes made an appearance and opted to wear the now slightly over-worn red and white dress by Stella McCartney. She teamed the dress with chunky nude Christian Louboutin sandals.

Kate Bosworth attended the premiere of new movie Life Happens last night in LA. The actress chose a pretty yellow pleated chiffon silk gown by Prada. The dress is an ideal spring-time look with the jewel embellishments adding to the pretty feel. Kate teams the dress with block heel sandals by Christian Louboutin.

Twilight star Ashley Greene appeared at a DKNY promotional event in Macy’s New York this weekend. The actress who plays Alice Cullen in the franchise is the new face of DKNY. She appeared dressed head-to-toe in a rather odd ensemble from the pre-fall collection; faux leopard jacket, camel leather skirt and red blouse. Whilst Ashley is the face of DKNY she is obliged to wear the label at promotional events however DKNY surely have a thing or two better than this look…

The stars turned out for the Nickelodeon Kid’s Choice Awards which took place last night in LA. The ceremony hosted by Will Smith celebrates the best in music and tv as voted for by Nickelodeon viewers. The red carpet usually provides a forum for more playful outfits than we’d normally see at awards ceremonies.

Kristen Stewart made an appearance at the ceremony where she looked chic in a cerulean blue lace belted dress by Stella McCartney. She teamed the dress with matching blue Barbara Bui suede pumps. Whilst this isn’t a hugely different look for Kristen, the colour is not one she is often seen wearing and is a nice look on her.

Selena Gomez went for a daring look in a white silk crop-top and embellished skirt look from the spring collection by Dolce and Gabbana. Whilst it is a little risque it is good choice for Selena keeping a young, fun vibe about it.

Katy Perry also chose an on-trend crop-top look, for Katy a lime green matching skirt and top by Gerlan jeans.

Emma Stone looked chic in a white draped bottom dress from next season’s fall collection by Antonio Berardi. She teamed the dress with Alejandro Inglemo wedges.

Victorious star Victoria Justice showed off a stylish look in a shorts and blazer look by the Olsen’s label Elizabeth and James. The coral colour is a nice spring palette however her choice of grey Valentino shoe-boots don’t really work with this look.
