this is such a long shot...but i have witnessed the power of S&B in action before and thought it was worth a try!
i saw a woman earlier this evening in a lovely summery dress - knee length, with a tie back, sleeveless, really bright vibrant red with a smallish print which involved some blue (possibly a bird) - i trailed her round laura ashley trying not to stare and waiting for a chance to compliment her but it never came as she was always too close to lots of other people and i was too shy 
it was knee length and she wasn't a teenager, am off to check out laura ashley summer stuff online, but would be so pleased if anyone can identify this for me - TIA
