Find Your Bamboo Pajamas Size: A Simple Fit Guide

If night comfort is a team sport, fit is the MVP. Many of us have a drawer of “almost right” PJs. This guide keeps it simple: measure once, pick your ease, then match features to your body and bedtime routine.

Step 1: How to Measure

Use a soft tape over thin clothing: bust over the fullest part; waist at your natural waist (where you crease when you bend); hips at the fullest part (about 7–9 in. below waist). For inseam, measure from the inner crotch seam to the hem on a pair of pants that fits you. Keep the tape level and snug—not tight. 

Step 2: Pick your “ease”

Clothes include “wearing ease” for comfort; some add “design ease” for a roomier look. Close-fit skims the body; relaxed-fit drapes for airflow—great if you run warm. For sleepwear, most families prefer relaxed to avoid cling and allow tossing/turning.

Step 3: Fit features that matter at night

● Fabric & stretch： GYS's signature fabric blend (92% bamboo viscose, 8% spandex) provides gentle stretch and a fluid drape, which can help reduce friction.

● Rise & waistband： Mid-to-high rise with a soft, encased elastic or drawcord stays comfortable through long nights and postpartum changes.

● Inseam & leg shape： Straight or relaxed legs with an inseam that clears your ankle keep hems clean and movement easy.

● Top length & neckline： Hip-length tops reduce ride-up; button fronts are breastfeeding-friendly for new moms.

Segment-by-segment quick picks

● Petite (≤5'4")： Prioritize shorter inseams or cropped legs; avoid pooling at the ankle that can catch and twist overnight.

● Tall (≥5'7")： Look for extended inseams or relaxed straight legs; check sleeve length.

● Plus/curvy： Seek relaxed hip and thigh, soft waistbands, and tops with side slits for easy movement.

● Postpartum/new moms： Button-front or wrap tops, gentle stretch, and flexible waist are your best friends at 2 a.m.

(Tip: sizing charts vary by brand, so always compare your measurements to the chart on the product page—don’t assume your usual letter size will map 1:1.)

Why bamboo-derived viscose feels different

Bamboo-derived viscose knits are smooth and breathable with great moisture handling—many hot sleepers can feel cooler in this fabric, while the drapey hand reduces friction on skin. (Experience varies.) If you prefer maximum structure, cotton jersey is a familiar alternative.

Care and fit longevity

To keep shape and handfeel: cold water, gentle cycle, avoid high heat; air-dry or low tumble; turn garments inside out to reduce abrasion and pilling. These habits help any knit last longer.
