件 is the measure word (or classifier) for many items of clothing.
In Mandarin, you usually cannot say 这衣服 or 那衣服 in standard grammar when you mean this piece of clothing / that piece of clothing. You normally need:
- 这/那 + measure word + noun
So:
- 这件衣服 = this item of clothing
- 那件衣服 = that item of clothing
件 is commonly used for shirts, coats, dresses, and other clothing items.
Because 那件 means that one.
The noun 衣服 is omitted because it is already understood from the first part of the sentence. This is very common in Chinese.
So the full comparison is really:
- 这件衣服比那件衣服更合适。
But Mandarin often avoids repeating the same noun when the meaning is clear:
- 这件衣服比那件更合适。
That sounds natural and efficient.
