I have been wear Brassieres Daily from January up to a few Weeks ago, it's over 100 degrees Farenheit or over 40 degrees Celsius and Brassieres get soaking wet and irritates me, I do still wear them when I am at home and at Night to sleep, I am beginning to understand when my Wife says it's too hot to wear a Bra. I wear Camisole and Bralette instead, still to wear a Brassiere, works really well in Cooler Climate. So do you wear a Brassiere in 100 degrees Farenheit??
