IMO definitely sisters though probably not identical. Can't say for sure because they don't stand side by side. See @ 1:25. Same earlobes, noses, heights, voices, same British accents. There's mutual touching but it's limited--that means same family. If they are non-twins, as I guess, then the right one, with the ass tattoo, would be the elder, based on how they interact. By the way, one of the best ways to verify mom/daughter, or sisters, or identical twins relationships is by the way they talk to each other. Especially mom/daughter. These two girls pass that test.
