As far as the colored pants trend goes, burgundy (or maroon) pants and olive pants are really the only two colors that have stood the test of time. I purchased my pair of burgundy pants from Madewell about two and a half years ago and have included them in 32 outfits since then (14 of which were shared here on the blog; click through the photos below to see the original posts). They are a favorite of mine in the fall and winter!
At first, you may think that burgundy doesn't go with a whole lot of other colors... Well, I've got proof that it goes with basically anything you throw at it! Though, interestingly, I haven't blogged an outfit featuring navy and burgundy together even though I've worn that combo in real life. Guess I'll have to change that. ;) Regardless, it works with any neutrals you prefer—grey and black or camel and brown. And it's fun to mix things up by adding a nice olive green, a blush pink, a mint green, or even a mustard yellow. If you're hesitant, pretend they're like regular blue denim and just start trying things on! You may surprise yourself with a new favorite color combination. :)
If you don't yet have a pair of burgundy pants but want a pair, I included a widget below with lots of options at a variety of price points!
