My dad was a firefighter and had to wear a navy blue 100% cotton T-shirt under his uniform. He used to buy plain navy t-shirts and send them in somewhere to be marked as garments.
I just bought some of the new garments today. I tried to order some last night but the site kept crashing. When I saw the crowd at my local store, I knew why. They had signs saying the new style top is coming in the stretch cotton in spring 2026, so hurrah for that.
Oh and to answer a question upthread about yeast infections above the waist, some women get them under their breasts, so yes if this top contributes to more air flow and less sweating, it’ll be great.
