A big trend for this Spring is pastel colours. A lot of shops I have been to recently have had a pastel inspired collection, like Topshop's Spring Equinox. Some of the clothes you will see are from that collection but there'll be items from other shops too...
Pastel coloured knitwear seems to be most popular as well as jeans (or trousers/pants in general), which are all useful for colour blocking.

It would be great if any international readers could comment below suggesting clothes websites that are more available to them. Because, although you can probably find most of the clothes I suggest elsewhere, I know some of the choices I pick aren't available to every country and I don't want to isolate anyone :)
EDIT: I found some lovely pastel-y dresses from River Island after I had posted this! Here they are...
