Why Sizing Is the #1 Complaint
Sizing mistakes are the most common reason buyers are unhappy with their MuleBuy orders. The problem is not that the items are bad — it is that they do not fit. Every factory uses its own sizing pattern. A size Large from one factory is not the same as a size Large from another. This guide explains how to measure yourself correctly, read factory charts, and choose the right size every time.
How to Measure Yourself
Chest / Bust
Measure around the widest part of your chest, keeping the tape level. Do not hold your breath.
Waist
Measure around your natural waistline, typically just above the belly button. Keep the tape snug but not tight.
Hips
Measure around the widest part of your hips. Stand with your feet together.
Shoulder Width
Measure from the edge of one shoulder to the other across your back.
Inseam
Measure from the crotch to the bottom of your ankle. For shorts, measure to where you want the hem.
Foot Length
Place your foot on a piece of paper, mark the heel and longest toe, and measure the distance in centimeters.
US Size vs. Factory Size
| Criteria | Option A | Option B |
|---|---|---|
| Small | US 34-36 chest | Varies: 36-40 depending on factory |
| Medium | US 38-40 chest | Varies: 40-44 depending on factory |
| Large | US 42-44 chest | Varies: 44-48 depending on factory |
| XL | US 46-48 chest | Varies: 48-52 depending on factory |
The Golden Rule
Never assume your usual size will work.
Always measure yourself in centimeters and compare every measurement to the factory chart. If you are between sizes, size up for items you want to layer or shrink, and size down for items you want fitted. When in doubt, size up — it is easier to tailor something down than to make it bigger.
Category-Specific Sizing Notes
Shoes: Always measure foot length in centimeters. Size up by 0.5cm if you have wide feet. Hoodies: Oversized fits are trending, but check the actual measurements. A tagged XL might be a standard medium in reality. T-shirts: Boxy fits require checking shoulder width, not just chest. Jackets: Measure with your intended layering underneath. Pants: Rise matters as much as waist — a low-rise pair will sit completely differently. Headwear: Most caps are adjustable, but check the maximum circumference.
Bottom Line
Sizing is the easiest problem to solve and the most expensive mistake to fix. Spend five minutes measuring yourself before every order. Compare all measurements to the factory chart. When in doubt, size up. The category pages on this hub include specific sizing advice for each type of item.
