Years of wearing shirts (and ties) for work mean they are a comfortable and known place for me. If blouses are too 'fancy' I find they irritate me. I like a collar that stays in the same place and doesn't flap around when I'm wearing it!! Although I am very drawn to the prettiness of blouses and have made a few - I'm not drawn to then wearing them. Something I hope to address in the me-made challenge in May!
I like the Cashmerette Vernon shirt, although I do make deeper cuffs on it nowadays. Made in a Tana lawn it feels lovely to wear. I made the Friday Pattern Company Patina blouse in baby cord last year and did wear that a lot in the autumn/winter. Thinking about it, it's perhaps not so much the style as the fabric choices that cause my irritation when wearing blouses. The baby cord was very well behaved when worn and didn't flap or float at all!! (I'm laughing at myself as I type this and feeling sorry for anyone who stumbles across the post!!)
I think the conclusion is that I need stable rather than flappy or floaty fabrics on my upper half - so that includes blouses. I like the swish of a skirt - but not a top! That's a distinction I hadn't appreciated before!
