WHICH BOSTON UNIFORMS DO YOU LIKE BEST? Here’s a chance to vote for your favorites.

Among the many things that define Boston sports — championships, legendary athletes, even the occasional spectacular failure — one of the constants has been the capacity to create iconography through uniforms.

Over the years, fans have come to identify their teams this way. If you think “green,” that’s the Celtics. Say “black and gold,” that’s the Bruins. The list goes on, with the favorite franchises known for their uniforms (even when there is a conspicuous change).

Different eras can be identified by different looks. When fans see classic photos of Red Sox players wearing red hats instead of blue, they know it’s probably the 1970s. Royal blue Patriots means the 1990s.

And while tradition largely has reigned, some of the memorable uniforms have been the exceptions. The “Pooh Bear” Bruins uniforms evoke polarizing reactions to this day, but nonetheless remain (in their own peculiar way) iconic.

The history of Boston sports uniforms has offered a panoply of fascinating designs and color schemes. It’s a rich tradition, worthy of celebration.

So this year, Boston.com is presenting readers with a simple question: What is the best uniform in Boston sports history? Of course, providing an answer is anything but simple.

In the spirit of March Madness, we have assembled a bracket containing 16 of the region’s most iconic uniforms.

Spanning more than 100 years of history, the field offers an array of worthy challengers.

The top four seeds represent some classics, with the 2004 Red Sox, the 1986 Celtics, the 1972 Bruins, and the “Dynasty Era” Patriots sporting distinctive looks that fans know so well. Beyond that, other versions of classics are in there, including the “Pat Patriot” uniforms of yesteryear.

The oddities have been given their place as well. The “Pooh Bears” are included, as are the 1908 Red Sox. Just to keep things interesting, some of the more striking 21st century iterations — Red Sox “City Connect” and Celtics “Statement Edition” — have been added too.

Looking beyond the four most popular Boston teams, the Revolution are represented by their bold inaugural uniforms from the launch of Major League Soccer (including the now-defunct “crayon flag” crest), and the Boston Pride’s brief but trophy-laden history also takes its place in the bracket.

To decide a winner, readers will vote round by round until a champion is crowned March 25 (Cast your votes at boston.com/uniforms beginning Sunday at 1 p.m.). The definition of “best” is enjoyably subjective. While the traditional uniforms have been given the top seeds, that’s by no means a guarantee of success. As is often the case in the NCAA brackets, dramatic upsets and general chaos can be defining qualities.

We expect nothing less in our own version. Enjoy this stroll through Boston sports history, and don’t forget to come back to vote again as the rounds progress.
