I need to find a smart dress to wear in the day for an event, not formal but think posh afternoon tea. I am a size 18. We have a 4 hour drive and nowhere to get changed beforehand so I am ruling out linen or linen blends because of creasing. I am not a huge fan of florals, I find they look frumpy on my frame.. No upper budget, I just want to feel nice. Any suggestions very gratefully received, thank you.
