How to Compare CHANEL Jacket Measurements Before Buying | UK
More than 92% of TC JAPAN customers return to shop with us after their first purchase.
The useful comparison is between garments measured on one consistent basis.
★ We do not rely on the tagged size alone. Each garment is measured to a consistent standard so that you can compare it with the actual measurements of a jacket you already own.
Comparing CHANEL Jacket Fit Online by Actual Measurements
Many sellers measure the shoulder from the seam between the sleeve and front bodice. Depending on the design, that seam may not mark the position where the actual shoulder sits.
The garment may have been measured flat without first smoothing wrinkles or correcting the angle of the bodice.
Once the measurements that suit you are clear, a later piece can be checked against the earlier one. On request, we can review the record of a previous purchase and discuss sizing with you.

Check these three points when choosing a size.
① Even with the same tagged size, actual measurements vary by era, design, material, shoulder construction and whether alterations were made.
② People of the same height, weight or usual size can have different balances across the shoulders, bust and waist.
③ Fit preferences also differ: some prefer more ease, while others want a neater line.

How to Measure a Favourite CHANEL Jacket
Choose a jacket that feels right when worn and, if possible, has a design similar to the one you are considering.
Fasten the buttons and place it on a flat surface. Smooth out wrinkles and any tilt without pulling the fabric before measuring.
① Do Not Use the Seam Line Alone for Shoulder Width
Most shops measure from the seam where the sleeve joins the bodice. That method can make it difficult to find a piece that truly fits.
When the seam sits outside the actual shoulder corner, the stated shoulder width becomes wider. When it sits closer to the neck, the number becomes narrower.
Therefore,
for both designs A and B, use the points where the actual shoulder corners sit, then measure between them along a gentle peaked curve.

② Measure Bust Width Straight Across from Underarm to Underarm
Fasten the buttons, smooth the garment so it is not wrinkled, and measure straight from underarm to underarm. Wrinkles or pulling the fabric can produce a number larger than the garment’s natural width.


③ Check the Armhole at the Same Position

④ Measure Sleeve Width at a Right Angle from the Underarm
Measure sleeve width at a right angle from the base of the armhole.

⑤ Measure Length from the Centre of the Shoulder to the Hem
Measure from the midpoint of one shoulder width down to the hem.

TC JAPAN’s Independent Size Guide Notation

When the tagged size and the fit suggested by the actual measurements differ, we may add a notation such as F36 (38 Large–40 Slim).
| Notation | Meaning |
|---|---|
| F36 | French size shown on the garment tag |
| 38 Large | Toward the larger end of a standard FR38 |
| 40 Slim | Toward the slimmer end of a standard FR40 |
Body proportions vary—for example, one person may have a fuller bust while another has narrower shoulders—so our independent size notation is only a guide.
First compare the TC JAPAN product-page measurements with a jacket you have measured using the method on this page.
Because TC JAPAN measures every garment consistently, we often hear from customers that choosing online is easier.
The reason is that the final check is made by staff who have spent years examining CHANEL clothing, rather than leaving each person to use a different measuring method.
Consistent measurements make it easier to compare a piece you are considering with the one you bought before.
This helps many returning customers shop with confidence.
Some customers keep the measurements of past purchases themselves. We also retain records for a period, so customers often ask, “What were the measurements of the jacket I bought before?”
Once you know the measurements that work for you, it naturally becomes easier to use those numbers when looking for another CHANEL jacket closer to your preferred fit.

When Matching Measurements from Another Seller Still Gives a Different Fit
There is one further point to keep in mind.
Some customers successfully compare a TC JAPAN jacket with a favourite jacket they already own, then later buy an item from another seller because its listed measurements look the same.
We sometimes receive the following comments about how those other items fit:
- “I followed TC JAPAN’s measurements when buying from another shop, but the fit was completely different.”
- “The shoulder width matched on paper, yet the shoulder line felt nothing alike.”
- “The bust width looked comparable, but the front felt tight when buttoned.”
- “It appeared close to a jacket I had bought here, but the other seller’s piece did not fit.”
- “I was reminded how much a consistent method matters.”
| Case | Result | Likely reason |
|---|---|---|
| Case 1 | The fit around the shoulders was completely different. | Many sellers measure the shoulder from the seam between the sleeve and front bodice. Depending on the design, that seam may not mark the position where the actual shoulder sits. |
| Case 2 | The amount of room changed greatly when the front was fastened. | The garment may have been measured flat without first smoothing wrinkles or correcting the angle of the bodice. |
These differences can arise when the measuring method or final-check standard is not the same.
Even when a shoulder or bust number looks identical, the result changes according to where the tape begins and ends and how the garment is arranged before measuring.
When buying valuable CHANEL clothing online, that difference matters. This is why TC JAPAN’s consistent measuring method is an important part of comparing fit.
