Following the Fashion on BGT

Amanda: Showcasing a new up 'do by celeb hair stylist Ben Cooke, Amanda's upped the fashion ante and then some in this peplum-detail dress by J'Aton. Could she work anymore trends!? The bondage beaded belt and plunging neckline may be a touch risque, but in a good way, girl's got talent (and cleavage)...oh and Chanel earrings, a Fendi cuff and YSL heels
Alesha: Is it a frock? Is it a top? (It's definitely not plain). Oh, and it's definitely a dress. Alesha added sexy strappy sandals and hair so sleek, you could almost do your make up in it - only, don't - you'll freak the poor lamb out.
Does she win? You know what to do (vote below).

ROUND 3: Power peplums vs Alesha's Aztec mini, which dress is best?

* ROUND 4 (9th May to calendar fans)
Amanda: Upping her game and then some, Amanda opted for a mullet dress with fluro accents and matching neon yellow nails, clashing her summery look with red hot lippie. Lovely.
Alesha: Looking just that little bit Mis-teeq-cle (NB we shoe-horned that one in, clearly) in another mullet dress, this time it's sheer, sparkly and by Falguni and Shane Peacock - and shoes plus belt by Julien Macdonald. Alesha looked smokin' hot but it wasn't plain sailing for her stylist Katie Greengrass who told ElleUk.com : "There was a slight problem with the alterations [of the original dress] and she can't go out looking less than a hundred percent perfect.
"When it's live telly, anything can happen, so we always have a back-up look we revert to if anything goes wrong at the last minute—and what a great back-up look this is!"
Amen to that. Alesha had been planning to wear Julien Macdonald, saying: "I really wanted to wear Julien Macdonald because he’s somebody I’ve worked with from the Mis-Teeq days" - well, Macdonald accessories is just as good, right?

ROUND 4: Both stars wore mullet frocks, but who wins?

* ROUND 5 (10th May to calendar fans)
Amanda: Woah-there! Amanda's got her pins out and looks HAWT in a metallic mini dress by J'Aton (again). The 41-year-old added strappy black Nicholas Kirkwood sandals and H Stern jewellery to her look plus slicked-down hair...but has she done enough to win the BIG BGT fash' off? Amanda shared the below exclusive backstage shot on her blog here - getting ready has never looked so glamorous!

Amanda shared this exclusive behind-the-scenes at BGT shot as she got ready for day 5..

Over to Alesha...
Alesha: Having declared the importance of supporting British labels, it's great to see Dixon wearing a vampish frock by famed famous fashion house Alexander McQueen. The singer added vintage gold sandals and Giles and Brother accessories to her look, plus Avon nail varnish in Pro Naked Truth, naturally.
A little bit ink-blot in design, what do you make of Dixon's dress? And does she trump Amanda? Let us know below...
