Have £250 M&S vouchers. Could spend it all on food but would like to have a bit more to show for it than that and do need some clothes as I have gone up a size and a half following medical treatment and none of my clothes fit or look nice anymore 
So I thought I'd spend half on wine and half on clothes or something.
Have gone up from a 10/12 to a big 14 and - worse - gone from a slender-waisted pear to a pear with a big gut (sausage?), so my usual default of nipped-in waists and skirts doesn't look nice. Been wearing giant cotton trousers and baggy t-shirts (beachwear basically), and think I need to accept I'm going to be this size for a while and try to dress for it a bit better.
Does anyone have any recommendations for nice, preferably natural-fibres, stuff from M&S? I was thinking maybe some colourful cropped cardis and vests but will consider anything.
Need 'everyday' clothes rather than work or eveningwear. Will be getting some pants - have a couple of nice bras in new size already. Will be ordering online and sending back stuff which doesn't suit.
Any pointers (or advice to spend it all on wine!), welcome!
