How to Choose the Right Nightwear Size for Women
Finding the right size in nightwear is just as important as choosing the right fabric or style. Whether you're shopping for a cotton nighty, a pajama co-ord set, a kaftan, or a short nighty, knowing your correct size helps you stay comfortable and confident. In this guide, we'll explain how to measure yourself, what each size means, and how to choose the best fit from 9shines Label’s collection.
Why Nightwear Sizing Matters
Unlike regular dresses, nightwear should allow easy movement, comfort, and airflow. A nighty that's too tight can be restrictive, while an oversized one might not look flattering. That’s why understanding terms like bust, waist, hip, and length is key when checking a nightwear size chart.
Proper sizing not only affects how your nightwear feels but also how it looks. Whether you’re choosing a breathable cotton nighty, a structured pajama set for women, or a flowing kaftan nighty, the right size helps ensure you feel relaxed and confident at home.
Inaccurate sizing can lead to discomfort, especially during sleep. Tight fits can restrict movement, while overly loose styles may not stay in place, affecting your rest. When you get the sizing right, your night dress for women doesn’t just become a bedtime essential it becomes something you look forward to wearing every day.
How to Measure Yourself for Nightwear
Use a measuring tape and note the following:
Bust: Measure around the fullest part of your chest.
Waist: Measure around the narrowest part of your torso (above your belly button).
Hip: Measure around the widest part of your hips and buttocks.
Length: Measure from your shoulder down to where you want the nighty or pajama top to end.
Shoulder: Measure from one shoulder bone to the other across your back.

What Do Common Size Terms Mean?
Free Size: Designed to fit a range of sizes (usually M to XXL) thanks to adjustable waistbands or loose silhouettes.
Relaxed Fit: Slightly loose-fitting for comfort and airflow.
Plus Size: Sizes 3XL and above. Check bust, waist, and hip measurements carefully.
What If I’m Between Sizes?
If you’re in between two sizes, choose the larger size for comfort, especially in nightwear.
For kaftans or short nighties, flexible fits like drawstrings or stretch fabric often accommodate slight size variations.
Additionally, consider the fabric type cotton tends to shrink slightly after washing, while Bizzy Lizzy and viscose blends usually retain their original size. So if you're buying pure cotton, sizing up can help avoid a snug fit after the first wash.
Lastly, always refer to product-specific charts, as sizing can vary slightly across categories like pajama sets for women, kaftan nighty, or night dress for women.
