Holly & Matt and Jess & Karl

First up is laid back Luke, who loves to dress in baggy jumpers and flat caps, against his girlfriend Phoebe, who he thinks makes too much of an effort and can't even go out for a takeaway without glamming-up. Then engaged couple Chris and Curtis take the stakes even higher by putting their wedding outfit on the line. Flamboyant Curtis wants to see Chris scrub-up more. If Chris loses he'll have to ditch the kilt he wants to wear to the wedding and if Curtis is rated less hot he'll have to give up his diamond encrusted suit.
