Cassie MacGregor, the hat designer we featured in the October Advocate, hosts a cocktail party at BarBelmont tonight. It’s part of a series of parties called "Mad Hatter Mondays," and there are only two left — one tonight and one Oct. 26.

The idea is to look cute in your cloche, fedora or tam and mingle with other hatted hipsters. MacGregor will be on hand with a stock of House of MacGregor originals. And even if you don’t buy one, she’ll let you try them on.
