OK guys. I think we all know by now that
Catherine, the Duchess of Cambridge
(that's Kate Middleton, BTW) can do a classic look better than anyone. This ponytail she sported this week while on the
royal tour in New Zealand
, accompanied by an
Alexander McQueen suit
), is a perfect example.
The last time we thought we could pull off a ponytail like this, it was probably 4th grade soccer practice. Duchess Kate, however, shows us how it's done. The trick to this pony is making sure it's not too high -- otherwise, we're verging on juvenile territory here. Though you can't see it in this photo, Kate also has hair wrapped around the part where the ponytail holder should be -- we love our Emi-Jays, but royal affairs probably don't call for casual accessories.
We don't know about you, but we're eager to test out this classic hair look for spring.
