Like mother, like daughter.

When Kate Middleton arrived at the East Anglia Children's Hospice (EACH) at the Treehouse center in Ipswich on Monday morning for her first ever public address, royal fashion fans were shocked at the Duchess' fashion choice. See more photos of Kate Middleton giving her first speech as a royal.

The 30-year-old's cobalt blue Reiss dress (from the label's 2008 collection) came straight from her mother's closet, and Kate even styled it the same way: with black pumps, a thick belt and matching clutch.

Carole Middleton wore the look to Ascot back in 2010, pairing the outfit with a feathered fascinator.

It's not the first time the Duchess has recycled an ensemble. The white Reiss dress she wore in her official engagement portrait made an appearance on Canada Day and she often swaps clothing with her sister Pippa.
