Ask three questions of the comment

  1. Which size and version did the writer buy?
  2. What do they normally wear or measure?
  3. Which part felt different: width, length, shoulder, sleeve or shoe opening?

A note that answers all three can help you use the chart. A bare “TTS” is a prompt to find that context, not a complete size recommendation.

Fit preference can explain the disagreement

CommentThe comparison still needed
“Size up for an oversized look”How much width/length the larger option adds and whether you want that look.
“Sleeves were short”Purchased size, sleeve starting point and the writer's reference garment.
“Narrow at the front”Shoe version, chosen label and the width concern rather than length alone.
“Usually M, chose L”The normal product/cut used as the reference and what changed in the chosen option.

Two people can prefer different sizes of the same garment without either chart being wrong. Keep their aims separate before counting which advice appears most often.

A repeated note is still one note

If the same sentence appears across several lists, compare the source album and purchased option. Copying can multiply appearances without adding another wearer's measurements. Repeated finds helps you read that situation.

When the note describes a different version, use it to identify a question for the version you want rather than treating it as a transferable fit test.

Turn the advice into a measurement choice

For clothing, find the specific chest, sleeve or length field that addresses the comment. For shoes, keep the US/UK/EU label and length definition attached to it. Clothing-chart fields and shoe-size fields explain how to compare those measurements.

If the chart and a well-described comment still conflict, compare the measurement bases. That is more useful than following “size up” solely because it is repeated.
