Dear Daria, Another super affordable offering by your company! As I have texted you before, folks with serious skin allergies have very few clothing options; only nylon-based undergarments work for me. These tights are "head and heels" above their N. American competitors. They are very soft and comfortable to wear. While I still must wear a thin nylon brief for some extra "anatomical" support, these tights are snug and comfy to wear throughout the day. While I will wear your nylon knee-high socks or hold-ups in the hot Canadian summers, these 60 Denier tights are perfect to wear the rest of the time with both casual and formal attire (great colour selection!). Their subtle reinforced toes and increased thickness decrease the chance of "laddering" that occurs with thinner, cheaper tights. I also love their thicker waistband, which significantly reduces "rolling", a curse with many other brands of tights! Once again, "two thumbs up" for a great product; I will be purchasing more pairs in the future. Lastly, providing the "size charts" is an awesome strategy, as different brands of tights size differently. Fondest regards to a great company!
