Having had leggings before where the waistband is around my hips (I have long legs) I popped into topshop.
And they have these leggings called high waisted extra long; they fit high on the waist (obviously) and totally envelope any muffin top, love handles - anything. They come right down to my ankles which is great, and the fabric is super-soft and feels really luxurious. For £15 a really good winter essential.
