I have a relatively small head - 20" / 51cm. Most size small bike helmets for women start at 21 or 21.5" / 52 cm. I'm loath to buy one on the internet without trying it on, but I'd really like to get a CUTE helmet. I have one now that fits, it's a "youth" size that I got at Scheels, I think. Nothing wrong with it, but I'd just like something prettier, maybe gray-purple to match my bike.

Does anybody know what bike helmet brands might carry really small sizes like this? I do like the equestrian-style look of the nutcase helmets, but having never worn one, I'm not sure if I'd find it comfortable or overly warm.
