The collection is amazing so it was worth it and now I really need to get back to work!.' She said: 'I have been waiting since 6am and although I didn't get any of the things that I wanted, I still spent more than £1,000. One City worker, 30, took the morning off work to get her hands on the Kardashian-loved designs - and even up splurging well over £1,000. She told FEMAIL: 'I waited that long and didn't get any clothes. She joined the queue of 200 people at 5am on Thursday morning and only has a ring to show for it. Nilima Shah, from London, was not as successful.

I am already wearing one of my purchases and feel good because people are selling the clothes for double the price already.' Doors opened at around 8.30am and I got everything I wanted. I didn't bring a sleeping bag or a tent, just stood and waited. He said: 'I have been queuing since last night - for nine hours - in the freezing cold. One fashion student, Daniel Murphy, 18, from London, told FEMAIL he had been queuing for nine hours to get his hands on the new range. Shoppers were seen patiently queuing outside the Regent Street stores before a crowd formed when doors opened. Studies of this response are encourage, not least because they will focus attention on the poorly understood relationship between parental care and offspring quality.People enter H&M during the Balmain For H&M Collection Launch in Florence, Italy Interest in abandonment and infanticide has diverted attention away from this alternative parental response to small litters. It is most likely to occur when opportunities for rapid rebreeding are limited, and when increases in parental care have strong effects on offspring quality. This strategy may allow parents to compensate for the loss of offspring by producing a small number of high quality individuals. Evidence is presented which supports this possibility.

I suggest that, under certain conditions, an alternative to abandonment and infanticide of small litters in mammals is an increase in total parental care above that seen in larger litters. For small mammalian litters, however, evidence that parents employ these behavioural strategies is sparse. Solutions to this problem which involve abandonment of the offspring or brood reduction, for example by infanticide, have received most theoretical and empirical attention.

The question therefore arises as to how parents should respond to unusually large or small litters. Although natural selection may favour the evolution of an optimal brood size, unpredictable environmental factors can intervene to render the brood either considerably larger or smaller than this optimum.
