Dollar innerwear is very comfortable innerwear for me. I'm using it from 2015 and still I'm using it now. It's price is not so high it's average price for me.
Fabric is very good it's feels so smooth and Comfortable to chest. I love to wear it. It's design is very good and not so tite to body not so narrow.
It's undergarments elastic is very good fabric and it's a long lasting elastic.
I didn't found any customer service of Dollar.
