Great looking but...
I bought this for 'Er indoors' as a Mother's Day prezzie along with the matching Bandana Neck Warmer. Lots of positive comments, especially from other women. Afterwards, she said that they were beautiful but rather tight around the top as she has large (runners) ankles.
This can be an issue with 'one-size-fits-all' - they have to stretch but retain their tension so they don't roll down. I would recommend 2 sizes to accommodate the larger feet/ankles. saying that, they will last ages, so good for longevity.
