Memoi Heather Tights are model MK-054. These Memoi microfiber tights are 50 denier. I stock them in gray which is really a heather gray. They have a two tone look to them. They run small, but a little bigger than the regular Memoi Winter Opaque Tights. These tights are made in both children's and women's sizes. If a woman doesn't want control top these can be a good option. To see the girl's sizes go to the Girl's section of the website.
