Why do Hipobuy size charts differ from US sizes?

Factories use Asian sizing standards which run smaller than US sizing. A 'Large' on Hipobuy may fit like a US Medium or even Small depending on the factory.

Should I size up for everything?

No. Always measure a garment you already own and compare to the flat-lay chart. Some items are already oversized and sizing up would make them unwearable.

How to Read Hipobuy Size Charts Correctly and Avoid Sizing Disasters

Why Size Charts Fail So Often

Size chart failures are the single most common cause of buyer dissatisfaction on Hipobuy. Unlike Western retail where a Large is roughly consistent across brands, factory sizing on the spreadsheet varies dramatically. A Large from one factory may measure 54cm chest width while another factory's Large measures 58cm. That 4cm difference changes the fit from fitted to oversized. Add in regional sizing differences, vintage-inspired cuts, and deliberately oversized streetwear silhouettes, and the problem compounds.

The solution is not to size up blindly. The solution is to stop thinking in sizes and start thinking in centimeters. Every size chart on Hipobuy should be treated as a flat-lay measurement guide, not a size label. Your job is to translate your body into centimeters, then match those numbers to the chart. It takes five minutes and prevents 90% of sizing errors.

Essential Body Measurements

✓ Chest / Bust: Measure around the widest part of your chest, keeping the tape horizontal

✓ Shoulder Width: Measure from shoulder seam to shoulder seam on a well-fitting shirt

✓ Sleeve Length: Measure from shoulder seam to wrist bone on a favorite long-sleeve

✓ Total Length: Measure from highest shoulder point to bottom hem on a reference garment

✓ Waist: Measure around your natural waistline for pants and shorts sizing

✓ Inseam: Measure from crotch seam to hem on a well-fitting pair of pants

✓ Foot Length: Trace your foot on paper and measure heel to longest toe in cm

✓ Foot Width: Measure the widest point of your foot tracing for width-sensitive shoes

How to Read a Flat-Lay Chart

Flat-lay charts show measurements of the garment laid flat on a surface, not worn on a body. This is crucial because a garment's flat measurement is always smaller than its body measurement. A hoodie with a 58cm flat-lay chest width will fit a body chest of approximately 108–116cm depending on the fabric stretch and intended fit. Most sellers include a fit recommendation like "oversized" or "slim fit" which tells you how much ease to add to the flat measurement.

Slim Fit Garments

Add 0–4cm to your body measurement. The garment will sit close to your body with minimal extra fabric. Best for tailored pieces, fitted tees, and athletic wear.

Regular Fit Garments

Add 4–8cm to your body measurement. Standard streetwear and casual cuts fall here. Most hoodies and sweatshirts in regular fit use this range.

Oversized Fit

Add 8–16cm or more. Many streetwear pieces are deliberately oversized. Check the seller notes. Some oversized pieces are already sized up and you should order your normal tagged size.

Boxy / Cropped

Chest is oversized but length is shorter. Measure your favorite boxy piece for reference. Chest may be 10cm+ larger than standard while length is 5cm shorter.

Regional and Factory Differences

Asian factory sizing typically runs one to two sizes smaller than US standards. A factory Large may fit like a US Medium. However, this is not universal. Some factories specifically produce for export markets and use Western sizing. Others produce for domestic Asian markets and run significantly smaller. The only reliable way to know is to read the flat-lay chart and compare it to your reference garment measurements.

Your US Size	Asian Factory Equivalent	Oversized Factory	Action
US Small (S)	Medium (M)	Extra Small (XS) or Small (S)	Always check flat-lay chart
US Medium (M)	Large (L)	Small (S) or Medium (M)	Compare chest and length
US Large (L)	Extra Large (XL)	Medium (M) or Large (L)	Note sleeve and length too
US Extra Large (XL)	XXL / 2XL	Large (L) or XL	Verify oversized notes
US XXL (2XL)	3XL–4XL	XL or 2XL	Contact seller for custom

Critical Warning: Never order a size based on the tag alone. "I always wear Large so I ordered Large" is the number one sizing mistake. The tag size is meaningless without the flat-lay measurement context. Always measure, always compare.

Shoe Sizing on Hipobuy

Shoe sizing is even more complex than apparel because different factories use different lasts (the mold the shoe is built on). A size 42 from one factory may fit like a US 9 while another factory's 42 fits like a US 8.5. The solution is the same: measure your foot length in centimeters, then match to the factory's insole length chart, not the tagged EU or US size. Add 0.5–1cm for running shoes and 0–0.5cm for snug-fitting fashion sneakers.
