The “ripples” you circled are **fabric puckering**—and based on how they look (clustered, slightly oval dents), this is most likely due to **heat + stretch denim reacting after washing**.
### 🔍 What’s happening in *your specific case*:
* The pattern looks like **pressure + shrinkage marks**
* It often happens when:
* Jeans are **washed then dried with heat**
* Or pressed against something in the washer/drum
* The stretch fibers inside the denim **tighten unevenly**, pulling the cotton and creating those dents
### ⚠️ Important:
Since it happened to **both pairs**, it’s probably:
* Same brand / same fabric type
* Or same washing method (temperature or dryer)
### 🛠️ What you can do now:
Try this—it sometimes helps:
1. Lightly **spray water** on the area
2. Use a **hot iron with steam**
3. While steaming, **pull the fabric gently flat**
👉 This can reduce the appearance, but may not remove it 100%
### 👍 Best way to avoid it:
* Wash jeans in **cold water**
* **No dryer** (air dry only)
* Turn jeans **inside out**
* Avoid overloading the washing machine

💡 Honest truth:
This is very common with **stretch jeans**, especially cheaper ones. You didn’t do anything wrong—it’s mostly **fabric quality + heat reaction**.
If you want, tell me the brand and I’ll tell you if it’s known for this problem 👍
