Practical QC handbook

How to check LoongBuy QC photos

Review the largest risks first: wrong product, wrong size, obvious damage and poor construction. Only then move into small details. This guide gives you a consistent order so one attractive close-up does not distract from a larger problem.

The review order

Product → shape → material → construction → details → measurements

Always check in this order. A wrong size or damaged panel matters more than a tiny spacing difference that will never affect use.

Step 01

Make sure the photo set is complete

Start by counting useful angles, not total files. A strong set normally shows the front, back, both sides, important closures, labels or tags, and category-specific measurements. Blurred duplicates do not add evidence.

  • The complete product is visible without packaging covering it.
  • Both sides or both items in a pair can be compared.
  • Important details are sharp enough to inspect.
  • A measuring tape is visible when fit or dimensions matter.

Catalogue examples with QC signals. Open the full evidence set before judging any item.

Step 02

Review shape and proportions first

Zoom out before zooming in. Check symmetry, overall length, width, panel shape, pocket position and how the item sits when laid flat. For footwear, compare both shoes, toe shape, heel height and sole alignment. For clothing, compare shoulders, sleeves and hem.

Fast symmetry check

Imagine a vertical line through the centre of the product. Matching elements should sit at similar heights and distances on both sides.

Step 03

Inspect material, texture and colour

Look across several angles for consistent texture and finish. Warehouse lighting can shift colour, so do not decide from a single photograph. Watch for unexpected shine, thin-looking fabric, crushed filling, colour differences between panels or surfaces that appear damaged.

Step 04

Follow seams, closures and hardware

Trace the main seam lines instead of checking one isolated close-up. Look for uneven spacing, skipped stitches, puckering, loose threads and panels that do not meet cleanly. Check zips, buttons, snaps, buckles and other hardware for alignment and visible damage.

Low concern

One loose thread that can be trimmed without opening a seam.

Needs evidence

A folded or shadowed area that prevents inspection.

High concern

Open seams, broken hardware, damage or clearly mismatched parts.

Step 05

Check labels, graphics and placement

Use detail placement as one signal, not the whole decision. Review centring, level alignment, spacing, print edges and embroidery density. Compare against a reliable reference image when exact placement matters, but keep construction and fit ahead of cosmetic details.

Step 06

Verify actual measurements

Never rely on the labelled size alone. Compare centimetre measurements with an item you already own and like. The measuring tape should begin and end at the correct points and lie flat rather than following folds.

ProductUseful measurements
Jackets & hoodiesChest width, body length, shoulder width, sleeve length
Trousers & jeansWaist, rise, thigh, inseam, leg opening
Shoes & bootsInsole length, outsole length, width where relevant
BagsWidth, height, depth and strap drop
Step 07

Use category-specific checkpoints

Down jackets

Check fill distribution, baffle symmetry, hood shape, zips, cuffs and visible measurements.

Sneakers

Compare both shoes, toe shape, heel alignment, panels, stitching and sole attachment.

Scarves & knitwear

Look for weave consistency, pulled threads, edge finishing, dimensions and colour across angles.

Bags

Review structure, corners, strap alignment, closures, hardware and interior condition.

Step 08

Finish with one clear decision

GREEN

Enough evidence

The correct item is shown, measurements work and no meaningful construction problem is visible.

PAUSE

Ask for more

A key area is hidden, the colour is unclear or an essential measurement is missing.

STOP

Do not ignore it

The item, option or size is wrong, or visible damage and construction problems are unacceptable.

Step 09

Request a specific extra photo

Do not ask for “more photos.” State the exact area, angle and measurement needed: “Please photograph the back graphic straight-on in neutral light,” or “Please measure the chest width from pit to pit with the garment flat.” Specific requests produce useful evidence.

Quick answers

LoongBuy QC FAQ

What does QC mean?+

QC means quality control. In this context, it refers to warehouse photos or other visual evidence used to check the received item before international shipping.

How many QC photos are enough?+

There is no universal number. You need enough angles to see the front, back, sides, important details and measurements relevant to that product category.

Can warehouse lighting change colour?+

Yes. Compare several photos and, when colour is important, request a neutral-light image rather than judging from one frame.

Should I rely on the labelled size?+

No. Compare actual centimetre measurements with a similar item that already fits you.

When should I request another photo?+

Request another photo when a key area is hidden, blurred, folded, poorly lit or missing a measurement needed for your decision.
