But let's face it, most plus size knitwear is not exactly stylish. The plethora of chunky boyfriend cardis and waterfall tunics just hide half your dress. So I have hunted down a few more creative solutions: add-on sleeves that will give you the warmth or coverage you crave without hiding you dress, something which is probably useful for more than just our plus size friends!
First up is Mary Portas and Charnos 'Armery' (from £7). Mary designed these tights for your arms as part of her 'mature woman' fashion collection for House of Fraser. They're basically a shrug made of tights, with the added bonus of shapewear-like sucking-in power, if you like that sort of thing. They only come in two sizes, but due to the stretchiness, should fit most body shapes.
M&S are the latest to get in on the act with their 'Flatter Me' (ugh) cupless armwear (£22.50) a similar concept to Wingz. It's been a big seller - they stock up to size 22 but the website is almost out - but there is also a bodysuit for a few quid more in the same style that's available in all sizes. I love a bodysuit under a dress anyway - it hides undies lines and gives a nice smooth finish.
Finally, for those who want even more coverage, or don't like the idea of a restrictive garment under their bra, there's always the good old shrug. Yours Clothing has a good cheap basic (£16) in loads of colours up to a size 32, and it isn't too frumpy or shapeless. My tip is to size up and fasten it with a vintage brooch to cleverly hide a neckline that reveals too much!
