I recently bought the Next stitch cardi, which at £35 wasn't too bad. In terms of styling, I like a long cardi to be long, rather than finishing right slap bang across the widest part of the thigh, like a big horizon with arrows on it pointing to them.
I also like a bit of femininity within an outfit, however casual or basic the pieces are, so I put a Topshop printed blouse under the cardi, in the same colour tones.
I was talking to a friend from Brighton the other day and we always have a little clothes chat as part of our conversation. "Bethy G," she said "What tips can you give me for what to wear this season?" Having discussed the boots/parka/Topshop being great for jumpers issue and bearing in mind that she has two young boys and a dog, I pointed her in the direction of coated jeans. They are a good alternative to jeans, a little push at the boundaries without knocking the fence right over, and more importantly with two children and a (slightly slobbery) dog, you can give them a bit of a wipe over and no one is any the wiser.
The ones that I am wearing were bought from Primark for £10 last winter and I've definitely had my wear out of them. In addition to the cardi which I have featured below, I've also included a couple of options for coated jeans.
Next stitch cardi (£35), which also comes in an oatmeal colour.
GAP coated biker legging jeans (£32.99 to £42.99)
NEXT coated skinny jeans (£36) which come in several colours.
If you're tempted to give them a go, do let me know how you get on!
