Denver Hayes is the Mark's Work Warehouse house brand. MWWH specializes in uniforms - mostly heavy duty clothes for outdoor workers, and scrubs for health care workers, as well as jeans. They also carry footwear such as safety toe workbooks, rubber boots, and other shoes for folks who spend lots of time on their feet and good quality socks and underwear - thermal and regular. They carry a smattering of casual wear, and recently some business wear as well as nice leather sandals, shoes, and boots. Alfred Sung has designed a line for them.
Well, they make a great 95% cotton, 5% Lycra bikini (other cuts as well) and sell it at a ridiculously low price. My set of 5 came in black, tan, white with black dots, white with black floral, and Black and Tan floral on white that co-ordinates with my tan and black bras. They come out of the wash beautifully, and have held up very well. I also like the jockey product, and have several pairs of this striped one - but it is not cotton.
