Corrected entry: How does Alfred get Barbara's measurements for the Batgirl suit before she even got on a plane to fly from England to Gotham City? He hasn't seen her in years and we can assume that Barbara didn't just voluntarily give her Uncle Alfred her measurements.

Correction: If you've been making clothes (or in this case Batsuits) for years, you can easily learn to tell someone's measurements by sight.
