Maternity fashion trend: Polka dots and spots as seen on pregnant Kate Middleton

Kate Middleton showed off her growing baby bump late last week in a gorgeous polka dot maternity dress from Topshop.

The Duchess who was touring the Warner Brother studio teamed up the £38 dress with a black Ralph Lauren blazer and simple black heels.

The dress, which we featured a few months back, sold out within hours of the Duchess showing it off. However, we think she's set a polka dot trend for the maternity world and predict big things for this print.
