The ladies shirt from Huber is of functional fiber and is very reminiscent of material from a solid swimsuit. Nevertheless, it is very comfortable, cool and looks more like a sports shirt as like underwear and is supported by me for sports and hiking. I ordered Gr.40, wearing else for D-Cup even at tops Gr.38-40. This has in the waist a little air, sitting at the bust thanks to stretchable material though tight, but without squeezing. For women who really need size 40, it may be too small or sitting very close. The straps are wide enough for a bra to wear underneath. Since the shirt is made of synthetic fiber, it still loses fit for delicate fabrics either color.
