It seems like burgundy and olive green are the two most unpredictable colors. I've been making my rounds to the local shops and none of them want to take anything in olive green. Ironically, I think olive green is one of my best selling colors. It has also happened (more than not) that when I drop off a batch of olive green pieces (against the boutique owners' advisement) they sell out.
Even stranger is the response to anything I make in burgundy. People ask for burgundy non-stop: they want everything in burgundy, but when I give them what they want in burgundy no one buys it - go figure. Case in point are my burgundy wine dresses with lace trim. A couple weeks ago I made a run of these dresses for Etsy and they disappeared. I even had to list one as a custom listing and do a special order for another. I also brought a batch in to my local shops and they sold just as well. This week when I put a new run up on Etsy they're just not moving.
Similarly, my inbox has been flooded with emails asking for my butterfly top in burgundy. Someone even went so far as to sketch it out and ask for it. So I made a size run for the locals. They did pretty good here in town. Keep in mind, no one locally asked for these. I just made them and put them out and they sold. Conversely, they have not been selling online, despite all the requests. This could be due to the photo, but I can't be sure. I might re-shoot on a live girl to see what happens. As of right now I'm calling it the burgundy mystery. I hate to put it that way since it's such a nice color and so many people look so good in it. It really should be a sure thing.
I kinda did some poking around and found that burgundy was one of the top selling colors for cars in the 1990's - yuck! I feel like burgundy interior gets hotter and dirtier than any other color. The pigments in dark red paints fade much quicker than other colors when exposed to excessive sunlight. Maybe I should have tried selling these pieces back in the 90's.
Regardless of popularity, mystery, or anything else, I really like burgundy. I'll probably continue to work with it for a long time. If you have any thoughts or observations on the color as it relates to clothing or anything else feel free to contact me.
