The people have decided: Kate's best maternity look ever.

And it has some tough competition.

If you’re wanting to replicate The Duchess of Cambridge‘s maternity look she wore yesterday, you’ll have to turn the clock back to the wee hours of this morning when online shoppers sold out the Madderson dress, crashing the site in the process.

So we guess your only option now is to become besties with Kate and ask to borrow it. Totally achievable.

The Duchess was attending her first official engagement of the year, helping to name a new art space for The Art Room, a charity she is a patron of.

Kate, who turned 33 last week, toured the school along with artist Grayson Perry. She also met with students, who greeted her by singing “Lean on Me” and presented her with an art room chair they built.

The $830, loose fitting navy dress she wore showed off a little bit of Kate's growing bump, which she tactically hid with her clutch through out the event.

She knows we're after that money shot.

Kate (or most likely her PR team) was quick to post snaps of the event on the family's new Instagram account.

Not that we're obsessively checking the account for selfies with Prince George or anything.

Cough.
