3週5日目 ほこりだらけ
Development・time・result
接続：N＋ずくめ
It's all, one continuous state
注意 / Note：だらけ often carries bad reviews; まみれ is an object that covers a surface; ずくめ is all one color or one whole type of thing.
比較 / Compare：Same song: 〜だらけ／〜まみれ. These models are often mistakenly chosen for each other — carefully read the 接続 and nuances above and then decide.
よく出る形 / Common form：名詞＋ずくめ。The number of nouns that can be used is very FEW: いいこと・黒・規則・記録. The difference between the two models above is that they can be used for GOOD things.
