I tend to look at the composition label of knitwear before I buy. If it's a high content or 100% Merino wool I know it's a good bet. Merino is a breed of sheep that is known to have one of the toughest yet softest and finest wool and they need to be sheared at least once a year as it's wool doesn't stop growing. The fine fibers mean it's great at regulating body temperature, hence it being used widely in performance sportswear, and because it's not a chunky yarn is great for Spring layering.
There wasn't much choice of merino wool jumpers available now as most brands are launching their summer ranges. Below is a grey cowl neck jumper from East, in the sale at John Lewis!
I'm also wearing my M&S multicoloured shawl, Accessorize tan leather belt and H&M grey cotton vest under my jumper,well it's not that warm! My jeans are a new purchase from Zara and as the trend for ripped jeans continues I've gone for a soft ripped look rather than the 'shredded' look a lot of celebrities have been seen wearing. My grey suede ankle boots are G-Star from TK Maxx so I've selected a similar pair from Next.
