Litbuy Sizing Guide: How to Measure and Compare for Any Category

Sizing mistakes are the single most common source of buyer regret in the Litbuy ecosystem. The problem is not that the sizes are wrong — it is that buyers assume their usual label size will translate directly across batches, factories, and countries. It will not. This guide teaches you how to take accurate measurements, read size charts critically, and compare against garments you already own so you can order with confidence.

Step 1: Take Your Body Measurements

Use a soft measuring tape, not a ruler or metal tape measure. Stand relaxed, not sucking in or puffing out. For tops, measure: chest (fullest part, tape level), shoulder width (across the back from seam to seam), sleeve length (shoulder point to wrist), and front length (base of neck to desired hem). For bottoms, measure: waist (natural waistline), hip (fullest part), thigh (fullest part of one thigh), inseam (crotch to ankle), and front rise (crotch to waistband).

Write these numbers down and keep them accessible. You will reference them every time you shop.

Step 2: Measure a Garment That Fits

The most reliable method is not comparing your body to a size chart — it is comparing a garment you love to the size chart. Lay the garment flat on a hard surface and measure the same points: chest width (pit to pit, doubled), shoulder width, length, sleeve length, waist, thigh, inseam, and rise. These flat measurements are what size charts usually list, and direct comparison is far more accurate than body-to-chart conversion.

Step 3: Read Size Charts Critically

Size charts vary by factory, not by category. A "Large" from one supplier may have a 110 cm chest; from another, it may be 120 cm. Always check the specific chart linked to the item you are considering. Look for notes about fit type: "oversized," "slim," "boxy," or "relaxed" change how the measurements wear on your body. An oversized large will feel very different from a slim large even if the numbers look similar.

Step 4: Account for Shrinkage and Stretch

Natural fibers like cotton shrink 2-5% after the first wash, especially in warm water. Synthetic blends stretch with wear, especially in waistbands and cuffs. If you are between sizes, consider the material: size up for shrink-prone cotton, and size true for stretchy synthetics. Pre-shrunk or sanforized cotton minimizes this issue but is less common in budget tiers.

Step 5: Verify with QC Photos

If you use an agent, ask them to lay the item flat and photograph the key measurements. A quick pit-to-pit and length photo confirms whether the item matches the size chart. This step catches the majority of sizing issues before the item ever ships to you.

Step 6: Understand International Sizing Conversions

Many Litbuy suppliers use Asian sizing standards, which typically run one to two sizes smaller than US or European equivalents. A "Large" in an Asian size chart may correspond to a US "Medium" or even "Small." Never rely on label size alone. Always convert through actual measurements. Some spreadsheets include region-specific conversion notes, but these are not universal — your own measurement comparison remains the gold standard.

Bottom Line

Never assume your usual size. Always measure, always compare to a favorite garment, and always verify with QC when possible. Sizing is not guesswork — it is a system, and this system works when you follow it consistently.
