There is quite a range of pink leather bags that can be used to carry laptops, leather is a strong, durable and flexible material that wears a lot better than plastic. Leather can be dyed in a wide range of different shades of pink, my personal favourite being baby pink, this goes well with baby blue.
Some people prefer a hot pink to make them stand out more, whilst this is a much starker colour it actually works quite well in leather. Whilst pink laptop bags can be used for more than just carrying your laptop and more often than not get used to carry all the other essentials until there is no room for a laptop. Guess it's time for a new bag.
