Whether you need a dreadlock Rasta hat or a Derby, they've got you covered.

This is a serious NYC institution and the people who work here are to hats what pharmacists are to meds. They really, really know their stuff!

This is one of Paris's best and most legendary hat makers and a shop I used to visit almost daily. This is their store in London and I'm so glad to see they've done the brand justice!

It's fitting that a new hat shop would open in what used to be the garment district. You can actually see your hat being made here which is kind of fun.

Long story short this over 100-year-old London institution was closed down when "developers" forced all the residents of the street out. Luckily a guardian angel came along to save it and move it to higher ground as it were. So happy to see them back in business! Their mascot is a smoking cat!

A gorgeous store in a gorgeous city. It's on a bit of a side street so be sure not to miss it!

Great upscale hat store that carries pretty much only the finest designers. If you want something really fancy, this is the place to go!

This store was opened by a Parisian in 1857 (and the staff is really ready to go home;), and still has all its original interiors.

Last time I was here I saw an order form sitting out for a member of the royal family. That's the kind of place it is in spite of the sale signs.

To give you perspective on how long they've been in business--the Titanic hadn't sailed yet when they opened. If you don't see what you want they can make it for you.

This is the sister, or rather, brother store of Marie Mercie. Great place to bring back a gift for the guy in your life!

This is one of Paris's most classic boutiques and that's really saying something in this city. If you're in the market for a hat, you could find no better place!

Now we're talkin'! This place opened in the 1920s in the Astor Hotel. Today it's where the hippest of the hip go to get their lids.

This place provides the hats for Mad Men and a slew of other shows.

Their motto is "Life's better in a great hat!" and I have to agree.

Gorgeous, warm hat store with the most fabulous staff.

Does this mean it's for classy ladies or the hats themselves are classy? ;)
