Tips to Build a Conscious and Functional Pregnancy Closet

During pregnancy, our bodies transition from trimester to trimester. And it is of paramount importance to wear clothes that help the baby bump grow comfortably. Another priority should be to look for maternity clothes made out of the best skin-friendly natural fabrics that are breathable and lightweight.

  • Flowy Dresses- Flowing fits and wrap dresses are amazing during pregnancy as they can accommodate your belly’s growth with all the room required.
  • Oversized Tees- Loose tunics and oversized garments made in organic fabrics are going to be your best friend during this period. Not only are these comfortable to lounge around, but they also allow you to stress-free nursing.
  • Leggings- Trust us, leggings are going to be your go-to bottom throughout this period. High-quality leggings have all the stretch you need to remain super-snug. Just adjust the waistbands below the tummy as you get bigger.
  • Jersey fabrics- Jersey fabrics are designed to keep up with the stretch. And they would happily fit into your growing curves. Yes, even during your 3rd trimester!
  • Organic fabrics- Organic fabrics like lyocell, modal, certified organic cotton, and responsible merino wool are extremely kind to the skin (and the planet). Maternity clothing made in these fabrics would undoubtedly keep you comfortable.
