Buying women's clothing and underwear online: how to choose wisely and avoid purchase regrets

Buying women's clothing and underwear online is easy, but an attractive photo doesn't tell the whole story. The wrong size, unclear material information or a coat that isn't suitable for the British weather can lead to your purchase sitting unused in the wardrobe.

To avoid this, watch out for three common pitfalls:

  1. Relying solely on your usual size. Sizes vary between brands, styles and countries. A size S from one brand can fit very differently to a size S from another.
  2. Confusing marketing terms with measurable properties. Words like "breathable", "durable" or "waterproof" are only useful if they are accompanied by material information, a test method or a technical rating.
  3. Ignoring the care instructions. A garment that requires a delicate wash takes more time than an item that can be thrown in the machine. Also, check if a jacket is tumble-dryer safe and whether elastane will lose its shape if washed incorrectly.

Which product details should you check?

1. Size, body measurements and room for movement

When shopping for clothes online, don't just look at the sizes from XS to 3XL; check the corresponding measurements in centimetres. For underwear, your waist and hip measurements are important. For jackets and coats, consider your chest measurement, sleeve length and whether there's enough room for a jumper underneath.

For example, the size chart for the Calvin Klein bikini briefs lists waist and hip measurements for each size. However, note that the product name mentions 3XL, while the chart shown only goes up to XL. This is a good reason to check the available sizes and the latest product information on the product page before you buy.

For a women's outdoor jacket, having space for layers is practical. A jacket that needs to fit over a blouse or a women's cardigan shouldn't be chosen based on chest measurement alone. Check the shoulder width and sleeve length as well.

2. Material and construction

The material determines how a product feels and how it should be cared for. For comfortable womenswear, cotton can be a great choice, while elastane provides stretch. A women's denim dress might feel more robust than a dress made from a lightweight blend. A loungewear set, on the other hand, calls for a soft, flowing fabric.

For underwear, be sure to check:

  • the percentage of cotton, modal, nylon or elastane;
  • whether it has a lined gusset;
  • the seams and elasticated bands;
  • the washing and drying instructions.

According to the product information, the Calvin Klein 3-pack bikini briefs are made from 90% cotton and 10% elastane. The description also mentions a lined gusset and an elasticated logo waistband. For the Calvin Klein thong, a composition of 82% recycled nylon and 18% elastane is listed. The product text mentions beechwood fibres, but the stated percentages and fibre names are not formulated in exactly the same way. Therefore, always check the final label and the current product page.

For a women's outdoor jacket, technical ratings are more useful than general terms. According to the product information, the PELLIOT jacket has a water column rating of 35,900 mm H₂O, a breathability rating of 16,000 g/m²/24 hours, and an abrasion resistance of 40,000+ friction cycles. These are the product specifications as stated in the product description and are not a guarantee that the jacket will keep you completely dry in all weather conditions. Also, pay attention to the zips, seams, cuffs and hood.

3. Use and care

A women's blouse for the office has different requirements than a women's outdoor jacket for cycling or hiking. A women's trench coat is a versatile outer layer, but it won't automatically offer the same protection as a jacket with technical waterproof ratings.

Before you order, check:

  • if the garment is machine-washable;
  • what washing temperature is recommended;
  • if the fabric can be put in the tumble dryer;
  • if ironing or dry cleaning is permitted;
  • whether the style is meant to be worn fitted or loose.

For instance, the care instructions for the PELLIOT jacket specify washing on a cold, gentle cycle, no bleaching, no tumble drying, and zipping it up before washing. This level of care is suitable for intensive use but requires more attention than a simple sweatshirt.

Useful combinations for your wardrobe

If you're buying women's clothing and underwear online, you can thoughtfully build a small capsule wardrobe. Combine a women's dress with a women's cardigan or a light women's trench coat for changeable temperatures. A women's blouse works well with both jeans and a skirt. For relaxing at home, a loungewear set and soft basics are ideal. If you cycle or walk outdoors, it's better to look for a women's outdoor jacket with adjustable cuffs, a hood and plenty of room to move.

For underwear, you can choose between women's bikini briefs and women's thongs. A bikini brief offers more coverage, while a thong can be less visible under close-fitting clothes. Calvin Klein underwear is available in various styles, but be sure to check the sizing, fabric and available colours for each product. If you're looking for women's clothing in sizes S to 3XL, always refer to the individual size chart rather than just the letter size.

Frequently Asked Questions

How do I determine my size when buying clothes online?

Measure your waist, hips and bust with a flexible tape measure and compare the results with the size chart for the specific product. Measure without pulling the tape too tight. For jackets and coats, remember to allow for a jumper or another layer underneath.

How long does women's underwear last?

The lifespan depends on how often it's worn, how it's washed, the drying temperature and the elasticity of the fabric. Wash according to the label, don't use a higher temperature than recommended, and avoid the tumble dryer if it's not permitted. Regularly check that the seams, fabric and elasticated band are still comfortable.

Is a waterproof women's outdoor jacket suitable for all types of rain?

Not necessarily. Look at the stated water column rating, seams, zips and hood. Technical figures are derived from a specific test method and don't tell the whole story about prolonged rain, wear and tear, or improper care. Always follow the product information and check that the jacket has the features you need before you buy.
