How does the maternity fit accommodate a growing bump?

The stretchy construction is designed to fit throughout all stages of pregnancy, with a slight front dip that accommodates a growing bump. As a general guideline, choose your pre-pregnancy size, or your current size if you are not pregnant.

Will these seamless maternity thongs show under leggings or fitted clothing?

The seamless construction and raw edges are designed to help prevent visible underwear lines under leggings and other fitted clothing.

What are these maternity thongs made of?

They are made from stretchy fabric containing 85% nylon and 15% spandex, with a 100% cotton liner.

What sizes are available, and how do I choose a size?

Sizes range from XS to XL. The chart corresponds to numeric sizes 0–2 through 16 and hip measurements from 37–38 inches for XS through 46–47 inches for XL. Measure around the widest part of your hips, below the bump if you are pregnant, to help confirm your size.

How should I wash and dry this maternity underwear?

Hand wash cold separately and lay flat to dry. Do not bleach, tumble dry, iron, or dry clean.
