On Saturday I couldn’t help but be disappointed watching Cheryl Cole walked onto the X Factor stage.

After her bold David Koma statement dress, her Jean Paul Gaultier Fall 2009 sheath dress was tame in comparison.

I can only believe that the criticism of last weeks choice got to her.

Her JPG dress was instantly recognisable by the X on the bodice, which was featured on many pieces in the Fall 2009 collection.

Her dress appeared to be modified slightly from the runway, as her dress was embellished with black crystals to allow the dress to sparkle on screen.

She paired her dress with black platforms.

The dress was just OK, but the hairstyle felt very dated.

She should’ve pulled it back to show off the X and details on her dress.

I loved Cheryl’s burst of colour on Sunday nights show.

The judge wore a Marios Schwab shift dress with crystal-embellishments in an opening in the bodice from the Fall 2009 collection.

She interesting paired her dress with nude heels.

Again I had a problem with the hair.  On Saturday night it felt to dated, whereas her hair on Sunday nights show looked like the stylist got his inspiration from a local school playground.

You may remember that Sienna Miller wore a watered down and nearly unrecognisable version of this dress earlier this year.

Whilst Cheryl Cole was going for the shock factor on Saturday’s X Factor show, Dannii Minogue’s look was more refined.

The judge who is mentoring the girls opted for another J’Aton Couture gown which was just a breath-taking as her gown last week.

Her asymmetrical one-sleeved glittering gown which was accented with a black thin belt, had a delicate lace bodice.

I loved her wavy updo and her soft make-up.

Black platform heels completed her look.

Her second look was a bold shouldered LBD by J’Aton Couture paired with a steel waistband and gold YSL peep-toes.

This look was less dramatic than previous looks but she still looked gorgeous, even with the slightly crimped hair.

In order to still show her respect for the poppy appeal, she wore her poppy as a bracelet.

It has been reported that Simon Cowell is unhappy about the Cheryl and Dannii stealing all the spotlight with their fashion choices.

Apparently he told the girl’s that it was a talent show and not a fashion show. I would say he should concentrate on remembering the contestants names.

On Saturday night on the X Factor it was Rock week.

I half expected Cheryl Cole to come out wearing a rock chick-inspired Balmain look, but she surprised everyone by wearing a black David Koma Fall 2009 mini dress with Tabitha Simmons Carla suede thigh-high boots.

Her halter neck keyhole dress had an interesting bodice detail of silver tone tubes.

The dress was an interest bold choice, and totally different from what we have seen on the Atelier Versace loving X Factor judge.

I wasn’t crazy about the look, but I didn’t hate it.

I would’ve dislike her look if her hair wasn’t pulled back. The bouffant wouldn’t have worked with this look.

Georgian born designer David Koma graduated in 2009 with distinction in MA Fashion from Central Saint Martins.

David’s pieces are sold exclusively online at Browns Fashion.

After Saturday’s show the press heavily criticized Cheryl’s David Koma dress, saying it looked like a pair of alloy wheels or dustbin lids.

This criticism may have been the reason why Cheryl toned down her look on Sunday night.

She still managed sparkle with her gorgeous smile and gold sequined Les Chiffoniers pants, which she wore with an asymmetrical black slashed top.

Slashed tops was one of the major trends of Spring 2010 fashion week.

She accessorized with a gold peep-toes, a selection of bracelets and a poppy.

One is a wannabee singer appearing on a talent show in the UK, the other is a singer appearing on a dancing show in the US.

Both performed wearing a Topshop spot mesh dress last month within days of each other – you can check out their performances below.

X Factor contestant Stacey Solomon was the first to wear the one-shouldered Topshop dress when she performed the Etta James classic “At Last” during week 2.

She wore her dress with Pied a Terre Atessa two-tone Mary Janes, and a black sash was tied around her waist.

10 days later Taylor Swift performed her newest single “Jump Then Fall” on ABC’s ”Dancing with the Stars” wearing the same Topshop dress.

She paired her dress with black peep-toes.

The dress is made more interesting with the sash, and the Pied a Terre two tone heels perfectly complement the dress so Stacey from Dagenham wins for me.

This dress is sold-out online, but I saw some in Topshop Oxford Circus this weekend so check your local store.

I have been talking about the X Factor a lot since it started 3 weeks ago here in the UK, but Italy also have their own version.

The gorgeous Asia Argento who you may remember was one of the judges during Cannes Film Festival this year, was also a judge on the Italian X Factor this week.

During Cannes she wore a lot of Armani’s Privé gowns, but on the X Factor she looked outstanding wearing a black and gold Sophia Kokosalaki Fall 2009 mini dress, with glossy black leggings and black booties.

I love Sophia Kokosalaki’s work, so I’m happy that she is getting a lot of celebrity love at the moment.

Rinko Kikuchi recently wore a very similar gold and black dress to the 22nd Tokyo International Film Festival Opening Ceremony.

Penelope Cruz became the first Spanish actress to win an Academy Award when she was handed a best supporting Oscar for her role in the Woody Allen comedy “Vicky Cristina Barcelona”.

After the ceremony – where she wore a very bridal vintage Balmain gown – she changed into a white asymmetrical Atelier Versace gown for the Vanity Fair Oscar Party in LA.

Still clutching her Oscar she looked stunning, as she kept her look very simple by adding diamond earrings.

Cheryl Cole wore the same white gown on the X Factor on Saturday night.

I wanted to love Cheryl’s look, but I was very put off by her hairstyle so Penelope wins this one for me.

Before I get to fashion, Rachel Adedeji made a total fool of herself on Saturday night as she morphed into Stacey Solomon. I was so embarrassed for her and annoyed she wasn’t in the bottom two.

Back to fashion.

It was week 3 and Cheryl Cole wore her 3rd Atelier Versace look in a row.

This time she opted for a stunning Grecian style asymmetrical Atelier Versace Spring 2009 gown with a thigh-high split, which we’ve seen before on the red carpet.

The gown was stunning, but I wasn’t happy with the hair.

I understand that her stylist was going for a goddess look, but the part that dangled loosely just bothered me all night, plus the silver headpiece was a bit much with her big hair.

Had she simply pulled her hair back and let the gown do all the talking, I would’ve loved this look.

Once again I struggled to find Dannii Minogue’s gown, but I just had to feature her because she was DROP-DEAD-GORGEOUS on Saturday night.

She wore a breath-taking antique silver embellished gown with exquisite Boucheron jewels and YSL heels whilst sporting old Hollywood marcel waves.

Definitely up for BDOTW.

On Sunday’s result show Cheryl wore a silver paillette Julien Macdonald Spring 2010 mini dress with nude panels and bold shoulders.

The silver paillette’s gave the dress a fish-scale type of look, which she paired with Rupert Sanderson Plato sling back peep-toes.

It was a bold choice for Cheryl, but it wasn’t my favourite look on her. It worked better on the runway.

I really hope she wears Look 32 as that was my favourite from Macdonald’s Spring 2010 collection.

Dannii blew me away again wearing a nude dress with a peplum on one hip, with a dripping effect of embellished details on her dress.

I have a feeling this one is by her favourite designer J’Aton Couture.

I hate pitting them against each other, but it was Dannii’s week.

Update: Dannii confirmed via Twitter that both of her looks are by J’Aton Couture.
