Coloured Jeans and Jeans in general are an easy option during the Spring/Summer time because they are comfortable but don't leave you feeling too hot or too cold. Plus they can be dressed up or dressed down.
As for coloured jeans they still give you that burst of colour that I would definitely recommend for this time of year!!
Here are a few of my favourites:
Asos Rose Skinny Jeans, Asos Spot Print Skinny Jeans.
Miss Selfridge White Super Skinny Jeans, Topshop Moto Camel Skinny Jeans.
