Question

When clothes tag says size xs/tp, what does the tp mean?

Answer 1

Tre petite.
It's essentially the same as extra small.

Answer 2

Answer:

When clothing tags say "tp", it means trés petit.

Explanation:

The expression "trés petit" or "tp", used for labeling clothes, comes from the French words trés, which means "very", and petit, which means "small". Thus, such expression is indeed the same as using the "xs" in English, standing for extra small. In countries where both languages are used, it is common to see both labels on the tag.
