Okay - you opened a thread that lay dormant for 7 years. I won't ask why. But I'll give you a bit of entomology: Though only bees are known for this, wasps, too (and yellow-jackets) are attracted by floral scents. If you wear aftershave - it likely has a floral scent. You are, in effect, inviting them. And what color clothing you wear also can invite them over to get a buzz. Yellow is their favorite. Wearing a darker color and forgetting the aftershave, cologne, perfume, etc - will reduce your likelihood of being sought out and stung.
