Apparently, in BJJ Pink Gis are acceptible - Check out this Atama Kimonos Special Edition Gi. I know that BJJ has a lot more flash and dash than Judo, and I know that BJJ is one of the fastest growing sports in the wake of the MMA explosion, but even if I were cross-training in BJJ, I couldn't deal with the patches and some of the more garish colors. I get white, I tolerate blue, and I understand black.
I would really be down on the Pink too, but then I learned it was specially designed for Kyra Gracie. Since she could very well tap me out any day of the week, and since she does it justice, I won't judge her. But please don't show up to my Judo class in a Pink Gi!
