I'm loving my sole light-grey boyfriend cardigan this year, for reasons Natalie and Denise have mentioned. So much easier to fit over an ever-expanding belly, so much easier to cool off said belly in without chilling the arms.
In fact, I am so keen on cardis this year that I just bought two more --- a woollen boyfriend style as well as a less-warm waterfall!
I've been kicking myself over my lack of decent (as in, can be worn outside the house) cardigans for several years. I find cropped ones as difficult as crew necks, maybe because I don't have much of a 'waist' (round-bellied rectangle here).
