plain jeans, like leggings

There are a couple of "style" (not technical) problems. 1) the clothes are too...ordinary; 2) jeans work best on the female figure when they're hugging and showing off the hips and butt. Having them part off like that just makes them look like an obstruction. 3) if you're going to have a figure slinking out of their jeans, it has to have a pose which emphasizes that. The current pose just makes it look disorganized. Not terrible, just unremarkable.

True, I didn't even think of that. XD

Let's be honest here. Since it's a cast-off, the jeans are going to be
coming off, which means that the complaint about the jeans really
won't matter. You can also just sew your own pair for her to put on
if you want something close to original.

I know they were probably going for a washed out texture, but the jeans look off to me. :S

I feel like T2 Art figures somehow lost their touch.... just doesn't feel the way they use to

First time I've seen jeans painted in a washed-out texture... for whatever reason, this T2 Art rendition isn't catching my eye.
