Light casual jacket

[Waggamamma]

I need a new light jacket for spring/summer. I'm currently on mat leave so budget is around £50 but will stretch to £70 for something really lovely.

To give you an idea I ordered this from Joules as I fell in love with it. But when it arrived it swamped me and made me look shapeless.

I'm 26, quite casual style and size 16/18. It must have a hood and be at least showerproof (due to living in Scotland it will probably rain all summer!). I generally wear jeans, converse, tshirt, cardi kind of uniform.

Any suggestions wise mumsnetters?

Have you tried Seasalt or Target Dry?

There was one in seasalt sale very similiar to the joules one but I don't think the cut will be any better. Never heard of target dry, I'll have a look. Thanks.
