Where to buy jeans for curvy girls

Hey everyone! I have recently lost some weight and I am struggling so hard to find jeans that fit me. I always have to wear a belt, but my jeans still fall because they are just. too. big. Where do you all buy your jeans from? Or do you get them tailored and how much does it cost?

My measurements are 36-25-42 so clothes shopping is hard and usually ends with me crying🙃 thank you all! 💖
