Active Maternitywear

Active maternitywear refers to clothing specifically designed for physical activity during pregnancy, incorporating features such as stretch fabrics, moisture-wicking materials, and supportive waistbands. These garments aim to accommodate a growing abdomen while providing comfort, mobility, and support for prenatal exercise and daily movement. Also see Maternity Activewear.

Adaptive Fit

Adaptive fit refers to garment construction that allows clothing to adjust dynamically to changes in body shape and size, ensuring sustained comfort and functionality. In maternity and nursing wear, adaptive fit is achieved through elastic panels, adjustable waistbands, stretch fabrics, or modular designs that accommodate pregnancy progression and postpartum recovery.

Adjustable Waistband

An adjustable waistband is a clothing feature that allows for changes in waist size using elements such as elastic panels, drawstrings, or buttonhole elastics. It provides flexibility to accommodate a growing or shrinking abdomen for increased comfort and prolonged garment use.

Antenatal

Antenatal refers to the period of time during pregnancy before birth, typically spanning from conception to the onset of labor. In the context of maternity and nursing wear, "antenatal" describes products designed to support the physical and lifestyle needs of individuals throughout pregnancy.

Baby Bump

A baby bump is the visible outward protrusion of the abdomen that occurs during pregnancy as the uterus expands to accommodate fetal growth. It typically becomes noticeable between weeks 12 and 20 of gestation, depending on factors such as body type, muscle tone, and number of prior pregnancies.

Bamboo Fiber

Bamboo fiber is a regenerated cellulose fiber made from bamboo pulp, known for its softness, breathability, and natural moisture-wicking and antibacterial properties. It is valued for its hypoallergenic qualities, thermal regulation, and comfort against sensitive skin, making it suitable for both parent and infant use.

Below-the-Bump

Below the bump refers to a maternity garment design where the waistband sits beneath the pregnant abdomen, typically on the hips or lower waist. This style is commonly used in pants and skirts to provide comfort, reduce abdominal pressure, and offer a secure fit during early to mid-pregnancy stages.

Use this quick comparison to understand the differences between over-the-bump, below-the-bump, and fold-down waistbands—so you can pick the fit that matches your stage, comfort level, and personal style.

They typically feature over-the-bump panels that provide gentle abdominal support, promote coverage, and accommodate a growing belly throughout pregnancy.

Inner Nursing Layer

An inner nursing layer is a discreet, built-in fabric panel within a garment that provides coverage and support during breastfeeding while allowing access to the breast through an opening such as a pull-aside or lift-up design. Common in nursing tops, this layer enables one-handed operation and maintains modesty during feeding.

Jogger Maternity Pants

Jogger maternity pants are casual, tapered-leg trousers designed for pregnant individuals, featuring a relaxed fit, cuffed ankles, and a supportive waistband. Typically made from stretchable, soft fabrics, they often include an over-bump or under-bump elastic waistband to accommodate abdominal growth and enhance comfort during all trimesters.
