There is no single size chart for everything ordered through Kakobuy. The platform connects you with seller listings, and those sellers can use different labels, patterns and measurement methods. A better approach is to compare the exact product's measurements with a suitable reference, record the option you choose and check the received item when useful evidence is available. This guide focuses on that process instead of a universal instruction to size up or down.
Start with the exact seller chart
Kakobuy's official sizing guidance notes that sellers can use their own standards and recommends choosing with measurements. Open the chart associated with the exact listing and version you intend to order. A chart from a similar-looking product is not a reliable substitute. Even familiar size labels can describe different measurements between sellers or product lines.
Check what each number means. Some charts describe body measurements, while others describe the finished garment laid flat. Units and measurement points matter as well. If the chart is an image, enlarge it enough to read the headings rather than guessing from a row of numbers. When a label remains unclear, ask for clarification before placing the order. The chart should answer a fit question, not merely look like reassuring documentation.
Choose a reference that matches the product
For clothing, a similar garment you already wear is often a useful comparison. Choose a reference with the fit and intended use you want from the new item. A fitted shirt and a loose sweatshirt are different starting points. Comparing every top with the same reference can hide the effect of style, layering and fabric stretch.
Measure the reference in a consistent way on a flat surface, without pulling it beyond its natural shape unless you are explicitly comparing a stretched measurement. Record the points used, not just the number. For example, note where body width or length was measured. This makes it possible to compare like with like when reading a seller chart or asking for a warehouse measurement. A small set of clear measurements is more useful than a long list taken inconsistently.
Prioritize the dimensions that control your fit
Not every measurement has the same importance for every item. For a top, you might care most about body width, length and sleeve reach. For trousers, waistband, rise, thigh width and leg length can influence different parts of the fit. A jacket may need room for the layers you intend to wear underneath it.
Decide which dimension would make the item unsuitable if it were wrong. That becomes your first comparison point. Then check the other important dimensions to make sure that solving one issue does not create another. A larger label might provide the body width you want while making the sleeves or length less suitable. Instead of treating size selection as a single number, view it as a small set of trade-offs tied to how you will use the garment.
Distinguish garment measurements from body measurements
A body's circumference and a garment's flat width are not interchangeable values. Likewise, a relaxed elastic waistband and a stretched waistband describe different conditions. Before comparing two numbers, make sure they describe the same thing. If one source measures around the body and another measures across a flat garment, you need to understand that difference before drawing a conclusion.
Be careful with automatic conversion advice that ignores the product. A general chart may help interpret units or familiar size systems, but it cannot replace the seller's actual measurements. Keep the original units in your notes where possible and make conversions explicitly. The most useful record says what was measured, how it was measured and which option it belongs to. A bare number without that context is easy to misread later.
Account for fabric and intended fit without inventing specifications
A garment's behaviour can affect how its measurements feel, but only use specifications the listing actually provides. Do not assume that a fabric stretches because the photograph looks soft or that an oversized model photograph means every size will fit loosely. Styling, model proportions and the selected sample size can all influence the appearance.
If your decision depends on a material property, ask for the relevant information. A measurement comparison can narrow uncertainty, but it cannot establish how an undocumented fabric will recover after stretching or change after washing. Avoid adding a blanket allowance to every item based on a general claim about all products from one country. Use the seller's information, a comparable reference and the fit you want from this particular garment.
Check footwear with the right size system
For shoes, identify whether the seller uses EU, UK, US or a centimetre-based reference, and check whether any US label refers to the intended sizing range. Kakobuy's guidance advises measuring both feet and using the larger measurement when selecting footwear. Compare that measurement with the exact seller's chart rather than assuming that the same printed size always represents the same fit.
Find out what a centimetre figure describes. Foot length, insole length and external sole length are different measurements. A photograph of the outsole cannot directly confirm the internal space available to your foot. Width and shape can also matter to comfort even when a length appears suitable. If the seller's information does not address a fit requirement that is important to you, keep that uncertainty visible rather than treating the conversion chart as a guarantee.
Record the option before you submit payment
Save the chosen size and any related version code together with the original product link. A single listing may have separate option groups, and the same size label can appear under different models. Review the selected combination on Kakobuy before paying so that your notes and the imported order describe the same item.
If you send an instruction, make it specific and consistent with the actual selection. A note should clarify the chosen option, not silently request a different one. When the listing does not offer the required size, seek confirmation about availability rather than assuming that a comment will make it available. This record also gives you a clear comparison point when the item reaches the warehouse and its label can be reviewed.
Use warehouse evidence to answer a precise question
When photographs are available for your own order, start by checking the visible size label against your selected option. If a critical measurement remains uncertain, ask Kakobuy whether a suitable measurement or additional view can be provided and whether a charge applies. Specify the start and end points, the units and whether the item should be measured relaxed or under another defined condition.
Do not rely on the background of a photograph as an exact measuring instrument when the decision is close. Perspective, folds and placement can affect interpretation. Kakobuy's inspection information also describes limits around measurement errors, so treat an image as evidence to interpret rather than a promise of perfect fit. If the new measurement uses a different method from your reference, resolve that difference before deciding the item is too large or too small.
Respond to a mismatch before planning the shipment
If the received label or measurement appears inconsistent with the order, compare the records first. Check the original chart, selected option, measurement method and relevant photograph. A clear mismatch and an unclear photograph require different questions. Describe what you expected and what the current evidence shows without assuming the cause.
Ask about the current handling options while the item is still in the relevant order or warehouse stage. Return and exchange conditions depend on the seller and applicable terms; they should not be treated as automatic or cost-free. Consider the practical options and their costs before approving the item for international shipment. Resolving the question early is easier than expecting the international delivery process to fix a fit problem already visible in the warehouse.
Build a reusable sizing note
After making a decision, keep a compact record for future reference: seller link, item version, selected size, chart values, reference-garment measurements and the result you observed. This is more useful than remembering that one brand usually fits you in a certain letter. It connects the fit outcome to a particular listing and measurement method.
For example, two hoodies can share a size label while one has the body width you want and the other has the length you prefer. Your note should explain which trade-off you accepted. If neither matches your needs well, choosing another listing may be more sensible than guessing between them. The purpose of a sizing process is to make the uncertainty smaller and explicit, not to promise that every online purchase will fit perfectly.
