How to Read a Performance Clothing Product Description

A product description contains at least three kinds of statement: verifiable specification, construction detail, and marketing language. Only the first two are useful for predicting how a garment will behave. Below: what to look for, what to skip, and the checks that catch a bad fit early.

Verifiable specification

These are measurable and can be checked against other brands: fiber percentage, fabric weight, compression rating, seam type, and rise measurement. These are worth researching.

Construction detail

These describe how the garment is made rather than what it is made from. Waistband construction, gusset presence, panel layout, and bonding are all real and all predictive. These are worth reading carefully.

Marketing language

These describe an effect the brand would like you to believe. Sculpting, contouring, second-skin, buttery, cloud-soft, and freedom-to-move are all unmeasurable. They are not lies; they are simply not information.

• Unmeasurable: sculpting, contouring, second skin, buttery, cloud soft
• Partially measurable: seamless, lightweight, moisture wicking
• Fully measurable: fabric weight, composition, rise, compression, seam type

A translation exercise

When a description says buttery soft, the measurable question is fabric weight and whether the interior is brushed. When it says second skin, the measurable question is compression percentage and elastane content. When it says sculpting, the question is panel layout and seam placement.

Every marketing term has a measurable correlate. You do not need to buy to find out.

The review-reading method

Reviews are most useful when they report on fit rather than on feeling. The high-value phrases are the ones about specific measurements and specific body types.

1. 01Height and size the reviewer bought, and whether it ran small or large
2. 02Whether the reviewer is describing a static fit or a movement fit
3. 03Any mention of the waistband rolling, gaping, or holding
4. 04Comments about the garment after more than a few wears

Be cautious with reviews from very short or very tall reviewers; sizing is more sensitive to height than to weight.

Questions worth asking support

• What is the fabric weight in grams per square meter
• Is the waistband bonded or sewn, and can it be altered
• Is there a gusset panel
• What is the compression rating
• Does this run small, true to size, or large

Specification tells you what it is. Construction tells you how it behaves. Everything else is the brand describing what they hope you will feel.

What to check before you buy for the reading product descriptions

Two pieces can look identical on the hanger and behave differently in the reading product descriptions. The checks below are the ones that catch it early. Black High-Waist Airlift Capri is the piece we would test them against first.

• Squat test in a mirror: the fabric should go opaque, not sheer.
• The waistband should sit flat at your natural waist without rolling when you fold forward.
• Check the inseam against your height — a 7/8 length on a tall frame is a crop.

The quick filter

If a product page gives you a fabric weight, a rise measurement, and a seam type, it is probably an accurate description and you can buy with reasonable confidence. If it gives you five adjectives and no numbers, buy it expecting to return it.
