December and February call for a relaxed smart vibe at work. (January, if you're in the office, is just a whole other ball game - see Casual Friday.) In the summer months you need a wardrobe that works. No sweat patchy-business shirts or hot blazers - you need to look sharp, but stay cool.
Enter my friend milano knit. Ugh, how much I love this fabric really cannot be over emphasised. No ironing, no creasing - fold it up in your gym bag and its happy, pull it out hours later and it looks great! No sweat patches (provided you buy a dark colour). And then culottes. so comfy, somewhat acceptable in the office.
Was this really comes down to is carefully walking the line between casual and office-approp. I say: add some heels and a striking red lipstick and you can nearly get away with anything. Give it a whirl! (Note: your boss may not agree.)
