Even though personally, I think that shirts and blouses are really pretty and I'm completely in love with them, it *is* getting cold. So I have to say that right now, the ideal is going for one of those chunky, oversized knits. ZARA have really nice ones which I've seen all over Lookbook.nu, for example.
There are a number of ways of successfully pulling off these oversized numbers. I do suggest opting for something figure-hugging and with minimal volume for the bottom part of your outfit. I generally try to avoid looking like an overstuffed soft-toy.
Here are a few of my favourite ways of wearing chunky knits and large shirts:
1. Worn with a plain pair of leggings, cargo boots and a nude coloured scarf (depending on your colour scheme!). I particularly like this, it comes off in a really cute way.
2. Worn with jeggings/skinny jeans and edgy accessories.
3. With a tube skirt and heels/wedge booties and some pretty jewellery to glam up the whole look.
