I'm loving DP at the moment, though I do agree about the dress sleeves - quite unflattering, and I do have slim toned arms. All of their t-shirt sleeves seem to be the same - not quite sleeves, not quite no sleeves.
I practically live in their Eden jeggings at the weekend.
I've also got some navy ankle grazers from their petite range for work, they've washed brilliantly and fit really nice.
Plus I get 10% NHS discount.
