Help, my team at work is shortlisted for an award which comes with a pretty big ceremony dinner and I have zero clue what to wear. My sector is very relaxed in terms of dress codes and I've always been a jeans, jumper, flats and no makeup kind of a girl. I now have under 4weeks to find an outfit for a posh London do which has me smart enough but not so out that I am out of comfort zone (any more than I will be already!). Just hit 40 and body confidence at an all time low, 5"7 and wear a 18, generally hourglass shape though with a mum tum. Thinking something in a dark colour, certainly no sequins or bright shades and nothing shorter than knee. Ideally under £100 hit me with suggestions please!
