The full noun phrase: number + classifier + noun + adjective + này (hai cái áo đẹp này)

When a noun has several words around it, they line up in a fixed order: number, classifier, noun, describing word, then này, đó or kia (this, that, that over there). "These two white shirts" is hai cái áo trắng này, literally "two piece shirt white this". Những or các take the number's place at the front: những cái áo trắng này (these white shirts).

An easy way to remember it: what counts goes before the noun (những, the number, the classifier), and what describes goes after it, with này or đó last of all.

Where này stands matters. Cái áo trắng này is a phrase, "this white shirt". Cái áo này trắng is a full sentence, "This shirt is white", because once này closes off the noun, the word after it becomes the statement.

Colours often come with màu (colour): cái nón màu xanh (a blue hat). Another describing word can go before the colour: cái áo mới màu đỏ (the new red shirt).
