Online shopping is commonplace these days – even when it comes to sleepwear. But how can you be sure that the pajamas, nightgown, or robe you order will fit perfectly? The wrong size can effectively detract from comfort and the pleasure of wearing them. That's why we've prepared a practical guide to help you precisely choose your sleepwear size without leaving home . We'll show you what to look for when measuring your body, how to read size charts, and what to avoid to avoid disappointment.
Why is choosing the right size of sleepwear important?
Comfortable and well-fitting nightwear is essential for restful sleep and complete relaxation after a long day. The wrong size can cause pressure, restrict movement, and even disrupt the quality of your sleep . On the other hand, styles that are too loose can drape unsightly or slip down, reducing your confidence—especially if you're opting for something more sensual.
The right size isn't just about comfort, but also appearance. Well-chosen nightwear accentuates your figure and allows you to feel feminine even in the comfort of your home . This applies to both classic pajamas and more elegant styles, such as sexy nightwear with lace details.
Online shopping at the renowned women's lingerie store Oh!Zuza gives you access to a wide selection of styles and sizes – but it's up to you to ensure that the lingerie you choose fits perfectly.
How to measure yourself correctly – step by step
Online shopping has many advantages, but you can't actually try on your chosen lingerie. Therefore, taking an accurate body measurement is the first and most important step to avoid making poor choices . This way, you can be sure that your pajamas or nightgown will fit your body perfectly – without any constriction or unsightly folds.

Here are the basic measurements you should know before choosing your sleepwear size:
- Bust circumference – measure around the fullest part of your breasts, preferably wearing a soft bra or no bra, standing straight in front of a mirror.
- Waist circumference – measure the narrowest part of your torso (usually a few centimeters above your belly button), without sucking in your stomach.
- Hip circumference – measure around the widest part of your buttocks, holding the tape measure horizontally.
- Leg length (if you are choosing trousers) – measure the inside of your leg, from the crotch to the ankle.
Remember to take your measurements carefully, preferably several times, just to be sure . This information will be crucial when you start analyzing the manufacturer's size charts.
Size charts – how to read and interpret them
Even the best measurements won't help if they're not used correctly. Each brand may have slightly different sizing standards , so it's crucial to consult the size chart available on the product page. Always compare your measurements with the manufacturer's specific chart—don't assume your size from one brand will be the same in another.
At Oh!Zuza, you'll find clear and detailed size charts for every product to help you choose. If you're on the border between two sizes, consider what you'd like to achieve – a more fitted or looser fit .
It's also a good idea to match the style to your expectations and the occasion. Here are a few examples:
- For those who love comfort and cosiness, the perfect choice will be the Bliss women's pajamas with long pants , whose satin viscose drapes beautifully over the figure and does not restrict movement.
- If you're looking for something sensual and more form-fitting , consider choosing a size closer to your body – like the Glow pajama with lace detailing , which subtly accentuates your curves.

Common mistakes when choosing a size online
Shopping for sleepwear online can be enjoyable and convenient—provided you avoid a few common pitfalls. Unintentional sizing errors can lead to disappointment and returns , which are easily avoided.
Here are the most common mistakes customers make when purchasing sleepwear online:
- Lack of measurements or relying on the "default size" – going by the size you wore a few seasons ago can lead to a poor purchase.
- Inaccurate readings from the size chart – omitting a specific style and cut when assessing fit.
- Choosing models that are too tight – in the hope of a slimming effect, which may result in discomfort.
- Excessive rounding of dimensions – precision is of paramount importance when it comes to fit.
- Failure to take into account the material – for example, viscose with elastane behaves differently than pure cotton, so the shape and stretchability of the fabric also matter.

What to consider when choosing specific styles?
Each style of nightwear fits the body differently, so when choosing a specific model, it's worth considering not only the size but also the cut and material. Romantic nightgowns with a looser cut will be more forgiving of the figure and will work regardless of minor weight fluctuations. For example, the subtle Stars loose midi nightgown , which beautifully flows into the body and allows for complete freedom of movement.

When it comes to pajamas, it's worth considering whether the model has an elastic waist, loose legs, or a fitted top. Styles like the Oh!Zuza Lullaby long silk pajamas offer not only elegance but also comfort thanks to the fabric's natural fit. Women's viscose pajamas, on the other hand, are lightweight, breathable, and perfect for everyday wear.
When choosing a bathrobe, it's a good idea to consider whether it should serve as a cover-up after bathing or a stylish addition to your home outfit. Fashionable women's bathrobes made from soft-touch fabrics not only hug the body but also look great – especially if you want to maintain elegance even at home.
High quality matters – better fit and greater comfort
When shopping online, we often focus on appearance or price, but it's the quality of the material and workmanship that determines the ultimate comfort. High-quality fabrics drape better, are more durable, and are less prone to deformation after washing . This is especially important when it comes to sleepwear, which should feel like a second skin – soft, breathable, and pleasant to the touch.
Oh!Zuza's fashionable women's pajamas include styles made of viscose satin, silk, and high-quality knits that fit snugly without feeling constricting. For example, the Stars short nightgown is sensual yet comfortable.
By investing in quality, you are investing in comfort and durability – and this translates not only into better well-being, but also into the joy of every evening spent at home.
How to choose your nightwear size online – summary
Shopping for sleepwear online doesn't have to be risky – just approach it with caution and be well prepared. Here are the most important things to remember:
- Measure yourself carefully and write down your current body measurements.
- Check the size chart assigned to a specific product – do not trust universal markings.
- Take into account the style, cut and material , because each of them fits the body differently.
- Avoid common mistakes – don't guess the size and don't round up dimensions.
- Choose quality that guarantees a better fit and greater wearing comfort.
