We spent a very pleasant 45 minutes wandering through this museum. Entry was included as part of the Grand Palace ticket & the museum is in the grounds. It includes some history of silk production in Thailand & features a large number of dresses worn by Queen Sirikit in both western & traditional Thai styles. We learnt that Queen Sirikit really loves Pierre Balmain! Oh & if you need cooling down this is the place ... It's all aircon!
