We recommend the PAIGE Women's Arellia jeans for your early to mid-pregnancy wardrobe. While the product description initially mentions "100% Cotton," the explicit call-out of "comfort stretch ecru denim" and "the perfect amount of stretch for a flattering fit" indicates these jeans offer the crucial flexibility you'll need. The high-rise, combined with a relaxed barrel leg, provides subtle waist ease and a comfortable fit around the hips and early bump, making them an excellent choice for your first and second trimesters. They allow for natural body changes without feeling restrictive or obviously maternity-specific. We particularly love the versatile ecru color, which offers a fresh alternative to traditional blue denim and pairs beautifully with a range of tops and accessories, ensuring they integrate seamlessly into your existing wardrobe.
