Compare the measuring method before comparing numbers

1. Choose a relevant reference

Use a garment or item you already like for the same intended purpose. Compare a layered jacket with a jacket, rather than trying to infer its fit from a thin T-shirt. For shoes, keep your foot measurement and a comfortable reference pair's measurements distinct.

Write down the preferred fit and intended layer. A loose casual hoodie and a fitted sports layer can both be comfortable, but they do not share the same measurement target. Your preference belongs in the record rather than being hidden behind a size letter.

2. Define each measuring point

Lay a reference garment flat without stretching it, unless you are deliberately recording a separate stretched measurement. Describe chest width, length, sleeve, rise or inseam using start and end points. Follow the seller's diagram where possible so the comparison uses the same convention.

Keep flat width separate from circumference. Doubling a flat garment width can provide an approximate finished circumference, but it does not turn the number into a person's body measurement or a comfort guarantee. Padding, lining and construction can change usable room.

3. Keep units and chart versions visible

Record whether the source uses centimetres or inches. One inch equals 2.54 centimetres; convert deliberately and keep the original figure beside the converted value. Avoid adding precision the original measurement did not support.

Save the chart for the exact version you selected. A source may group several fits or constructions on one page. If the chart does not identify which option it covers, ask before applying it. Missing information is a question, not an invitation to borrow another seller's chart.

4. Work through a comparison

Example only: a reference T-shirt measures 54 cm across the chest and 72 cm in body length. A candidate chart lists 56 cm and 68 cm. If the measurement methods match, the stated difference is 2 cm wider and 4 cm shorter. That describes an outline; it does not prove how the shirt will drape or feel.

A different example: a pants chart lists 'waist 36–44 cm' without explaining the range. Ask whether those are relaxed and stretched garment widths or an intended body range. Do not compare an undefined range with a single reference measurement.

5. Record the unresolved fit question

Add the source, selected size, measurement method, reference figures and unanswered question to your CSSBuy spreadsheet. Ask for the one measurement that would change your decision, using a clear start and end point. Avoid vague requests such as 'is this true to size?' when you can describe a specific comparison.

CSSBuy's official order flow includes choosing size and colour. Carry your resolved option into that stage through the CSSBuy shop guide, and use the warehouse checklist if a later photo raises a new question.

• Reference item and intended fit.
• Exact chart version, units and measuring points.
• Selected option and the question still unanswered.
