Does anyone else find it inappropriate that there are "boyfriend jeans" for little girls?
The concept of boyfriend jeans is that they fit like your boyfriend's jeans do. I'm just saying, I don't think there are any situations where it's appropriate for a child to have her boyfriend's pants on. I'm not going to elaborate.
You can refer to them as "relaxed fit" or "straight leg" and have the same effect without the inappropriateness.
