Perrie and Jonnie embrace the party theme. Photo: Rex
Perrie embraced her rocking role with gusto, piling on the accessories to go with the red fright wig while her brother Jonnie took top-hatted Guns N' Roses guitarist Slash as his style inspiration. He seems to have muddled his metal though - we spy an Iron Maiden tee under that double belt action!
What do you think of the pair's costumes?
Compare and contrast Toyah's hair in the video below:
And if you're looking for some ginormous hair inspiration, check out the gallery below:
- Adele<p> For big hair, vintage style, look to Adele's bouffant from the MTV Music Awards 2011. You'll need rollers and plenty of hairspray to keep the pumped up do in tact.</p>

- Agyness Deyn<p> Agyness is the queen of the boy crop, but she showed short-haired girls how to add height to their locks at the Royal Academy's Summer Exhibition back in 2009.</p>

- Beyonce<p> If you want to avoid back-combing, Beyonce's corkscrew curls are a stylish but perfectly tousled alternative.</p>

- Chaka Khan<p> When it comes to volumised hair, Chaka Khan comes straight in at the no.1 spot. If you want to channel the soul diva style, it's the only way to go.</p>

- Cheryl Cole<p> As Cheryl Cole touched down in the US to launch the <em>X Factor</em> this summer, no one could fail to notice her brunette mane. Nothing says, "I've arrived" like big hair.</p>

- Drew Barrymore<p> At the 2009 Golden Globes, Barrymore sported one of the most impressive blow dries that we've seen on the red carpet. It's also one of her best hairstyles to date.</p>

- Nicki Minaj<p> When Nicki Minaj attempts to do blonde bombshell, she doesn't hold back. You could loose something in those locks...</p>

- Rihanna<p> Rihanna went rock chic in 2011 with a head full of ringlets that rivalled Chaka Khan's.</p>

- Jennifer Lopez<p> No one does glossy, A-list hair quite like J-Lo. Tumbling waves are one of the easiest ways to add volume to long locks.</p>

- Dolly Parton<p> For a true hair icon, look no further than the one and only Dolly Parton. Think lots of layers, plenty of height and if you're not already blonde, hair dye.</p>


Okay so she's far too young to remember Toyah Willcox* but that didn't stop
