I'm having a really tough pregnancy, and so for morale purposes I thought I would treat myself to a nice silk maternity blouse of some kind, that would look suitably seasonal on Xmas morning, and maybe would be wearable to an evening drinks do as well, possibly over black trousers. I only seem to be able to find drab t-shirts out there. Please help me find something nice! I'm a size 16 btw.
