My Christmas events this year are lunches rather than dinners, so no party dresses and sequins, but I'll need something a bit dressier than my normal office wear or weekend jeans. I've got a pair of dark grey cords that could possibly fit the bill but I'd need a suitable top to wear with them. Pretty much everything I've seen advertised as Christmas/party wear seems to be made of polyester/acrylic (which I really want to avoid). Ideally I want long sleeves and I'd prefer a top to a jumper as I think the venues will be warm, especially after a glass of wine. Size 16, nothing clingy or low cut, not keen on busy prints, budget up to about £50. Any suggestions? Thank you!
