Tesco, £18. They're labeled as "slouch" style but really aren't a baggy fit apart from below the knee.
They come in three different lengths so good for short arses like me. They're comfy, only thing is they seem a bit thinner than normal jeans. Which I think is maybe why they fit well and are comfy just not sure they will be very hard wearing. So I've been back and got a 2nd pair as I love them so much. They make my bum look smaller and look trendy. The jeans are trendy that is, not my bum.
They're the ones with a belt that comes with them - either a pink belt or a turqouise belt.
