Suit, what suit? I do cutouts sans veil or gloves and my work uniform is black. I came up hearing the white only thing. My beek mentor wore the full deal right down to thick cow hide gloves and I thought that was the only way to go. Made my first "suit" out of a cast off prison jacket (complete with Alabama Dept of Corrections on the back) and wore the thickest white painters pants I could find. First to go was the gloves as I hate gloves for anything then the jacket went after the sheriff's deputy had a few questions for the "escapee" working his bees. Pretty much lost the veil when I took to training technicians as I almost always had to loan out the jacket plus I always waded in to demonstrate that bees are not to be feared.
I still use common sense and keep the gloves and veil in arms reach but don't feel the need for them.
Of course I recommend all newcomers and anyone who really feels the need to always suit up. My two year old has her own full suit and gloves and I reqire her to wear it. As for color, go with what you like but light colors just seem right to me plus being cooler. If I had to buy one though I like the camo full suit.
