I ordered some leggings for the first time recently from Long Tall Sally - I am 6ft1 and it’s a struggle to find clothes that fit. Firstly, the quality of the leggings is amazing and better than all other brands I’ve tried. They arrived quickly, although they used MyHermes as a courier which I dislike. They are quite expensive compared to other brands, but I do think you get what you pay for in terms of quality. I’ve not had to use their customer services or return anything so I can’t comment on that.
