How to choose women’s and girls’ clothing without making a costly mistake: a practical guide to fit, materials and sizing

Buying women’s and girls’ clothing online may seem straightforward, but product photos do not always show how a garment feels in everyday use. For example, the wrong size in a women’s bodysuit can pull uncomfortably at the crotch. With women’s shapewear, a firm fabric can become uncomfortable during prolonged wear. For girls’ clothing, inaccurate size charts or stiff seams can sometimes cause irritation.

By carrying out the right checks beforehand, you can compare products based on concrete features rather than marketing language.

Three common pitfalls when buying clothing online

1. Relying solely on the standard size

A size 140 usually refers to a body height of around 140 cm, but the fit can vary between brands and models. A girls’ tank top, girls’ starter bra and girls’ leggings may also use different sizing. Therefore, always check the size chart, bust measurement, waist and length whenever this information is available.

The difference between a close-fitting and a loose fit is also important for women’s clothing. A seamless bodysuit with plenty of stretch may fit differently from a lace bodysuit with less elasticity.

2. Confusing ‘seamless’ with completely invisible

A seamless bodysuit often has fewer visible seams, but fastenings, leg openings and edges may still show under thin clothing. So look at the construction: does the model have a smooth finish, a thong fastening or a wider bottom section?

‘Seamless’ is not a guarantee of comfort with shaping bodysuits either. The level of stretch, pressure distribution and position of the fastening determine how suitable the garment is for everyday use.

3. Overlooking the material and care instructions

A fabric containing a high proportion of elastane can be flexible, but it often has specific washing requirements. Some products may only be hand-washed and must not be tumble-dried. For shapewear with bonded sections, machine washing can damage the construction.

With girls’ clothing, pay particular attention to the cotton content, washing instructions and stretch. A set made from 95% cotton and 5% elastane feels different from a synthetic stretch fabric.

These specifications deserve extra attention

Fabric composition

The product description explains how a garment is made. Cotton is often chosen for everyday girls’ clothing, while nylon, viscose and spandex are commonly used in bodysuits and shaping underwear.

Examples from the range:

  • The Chicco tank top 2-pack is described as 95% cotton and 5% elastane.
  • According to the product information, the likeuu girls’ starter bra consists of 47.6% viscose, 47.6% cotton and 4.8% spandex.
  • The Feelingirl lace bodysuit has an outer layer made from 87% nylon and 13% spandex, plus a lining made from 62% nylon and 38% spandex.

A higher percentage of stretch fibres does not automatically mean that a product will be more comfortable. The fit and tension of the fabric remain decisive factors.

Stretch and fit

Check whether a product is described as slim fit, high-elastic or suitable for a particular size range. The likeuu starter bra, for example, lists sizes 140, 150 and 160, with guidelines for bust measurement, weight and body height.

For a women’s bodysuit, also check:

  • the length of the torso;
  • the shape of the neckline;
  • the width and adjustability of the straps;
  • the type of gusset and fastening;
  • the size according to waist and hip measurements.

A popper fastening may make the garment easier to put on and take off. With a lace bodysuit featuring several poppers, it is sensible to check whether the fastening is practical for the intended use.

Support versus light shaping

Terms such as tummy control, slimming and shaping refer to the construction of the garment. They are not medical claims and do not mean that a product treats a physical problem. According to the product description, a model may, for example, feature a tighter weave around the waist and tummy for light shaping.

So first decide what you need: a soft layer under an outfit, light support beneath a dress or a decorative lace bodysuit. A highly elastic shaping bodysuit is not automatically suitable for wearing all day.

Frequently asked questions about women’s and girls’ clothing

How do I choose the right size for girls’ clothing?

Use body height as your starting point, but also check bust, waist and hip measurements. With Chicco, for example, size 104 may correspond to approximately 4 years, while another manufacturer may use a different fit. If in doubt, measure the child and compare the result with the size chart for the specific product.

How long will a bodysuit or shapewear last?

Its lifespan depends on how often it is worn, the tension placed on the fabric and how it is cared for. Hand washing, cold water and air drying help reduce strain on the elasticity and fastenings. Always follow the care label; for some models, bleach, ironing, tumble drying and dry cleaning are not permitted.

Is a shaping bodysuit suitable for everyday use?

This varies according to the design and personal preference. Look at the stated level of shaping, the material, the fastening and the size. A model that provides light shaping and sufficient freedom of movement may be practical for some outfits. Stop wearing the garment if it feels tight, rubs or restricts your movement.
