We usually think of onesies as cuddly and fun, not charitable! But a couple of high-profile Aucklanders donned onesies for a cause last night during the Big Sleepout.

The Lifewise Big Sleepout raises money for, and awareness of, homelessness. GrabOne isn’t involved, but when we saw Auckland MP Jacinda Ardern  tweet she was thinking of wearing a onesie, we thought we could help out just a little bit.

Thanks to Crazy Sales, we sent out onesies to both Jacinda and Vaughn Davis. Don’t they look great?

But were they cozy? We think they were! When asked if her onesie was warm enough, Jacinda tweeted:

We also spotted Jacinda in her onesie in the Herald – read more about that here.
