No, I’m not talking about the actual stick rubbing off. It actually bleaches out the “pits” of my black work uniform. I had the same trouble at my old job with dark blue uniforms.
I’ve only been working here for three months I don’t want to have to spend $40 for two new shirts 4 times a year.
Has anyone else solved this problem? I’ve tried three different brands and have the same trouble with all of them. 
Try Certain-Dri. You apply it at night before going to bed, and then use regular deodorant (not anti-perspirant) in the morning. Definitely works for me, and I used to have the same bleaching problem.
Wouldn’t it help to wear a t-shirt under your uniform?
Maybe get a bigger size shirt? Try different deoderant, something all-natural?
Dress shields. Oh, the horror!
Probably…my concern there, though, is that the environment that is already warm BEFORE even figuring in my long sleeve black shirt and black polyester pants, is now going to have a second layer.
Working on it. I’m up to my 3rd brand, still no dice. Will continue the search though. Thinking of trying PAN9’s suggestion though.
I had that trouble for years. I solved it in the short term with t-shirts as a sacrificial lamb while I worked my way through different anti-perspirants. Finally found Arrid XX unscented and have been using it for 15 years or more.
As a caution, I find Certain-Dri bleaches too (it bleached the pits out of my pyjamas), so you must wait until you are completely dry before putting any clothes on. You use it before bed anyway, but wait before putting on your PJs!
But, as for preventing wetness, it’s brilliant!
Abandon anti-perspirants.
Use deodorants.
Or talc.
I’m planning on getting those for job interviews just because of nervous sweating. I’m hoping they still carry them at the drugstore but I’ve identified an on-line source if I have to go that route.
Oh, as far as the OP, perhaps a clear gel antiperspirant?
Bzzt.
You will be *cooler *with a light cotton undershirt on. Even though it’s an extra layer, it’s an extra breathing, wicking layer which will absorb that sweat and move it away from your body, unlike your (I’m assuming) part poly long sleeved shirt which holds all that sweat onto your skin and ferments it.
Think of all the layers this guy is wearing. Layers don’t always make you warmer. It’s more about the type of fabric than the number of layers, and cotton underneath cotton/poly is cooler than cotton/poly or just poly alone.
