You know, I've been dating for over forty years and I never heard of this 'cuffing season' nonsense before I came on SoSuave.
I guess that only those who specifically go out to chase skirts notice more or less attention, but I never noticed getting less attention in certain months beyond the ordinary (you get more attention in late Spring, Summer, and early Autumn, because you can show more of your body than in the bundled-up winter months). And I don't need to rely on my body to attract women, so I do pretty well in the winter. Conversations flow like usual and being a happy person during the grey winter months can definitely make you stand out from the crowd and elevate your attractiveness.
I think these 'cuffing seasons' are just anecdotal incidents blown-up to theoretical proportions. No 'season' has that much influence on making connections with attractive women.
