Finally, I found what I had been looking for!
I went to the mall to find a perfect stretchy pair of jeans, but I could find none. If there was any, it was too expensive. Therefore, I tried to buy these jeans because of their reviews. The price was pretty low, so I didn't expect a lot. However, when they arrived, I fell in love immediately. They fit me perfectly. The color is also darker than the picture which I prefer. The jeans are so comfortable that I could sleep in them. Highly reccomend!
