Used in both speech and writing, mostly in a limited set of set phrases such as 黒ずくめ, 白ずくめ, いいことずくめ and ごちそうずくめ. It stresses that something is uniformly made up of one thing, and it is often neutral or positive. Unlike だらけ, it is not inherently negative, and unlike まみれ, it does not describe a substance smeared on a surface.

• だらけN3だらけ emphasizes an excessive amount spread all over the surface and often carries a sense of annoyance, typically attaching to words like 泥, 血, 傷, or 間違い; ずくめ stresses the overall impression of everything being uniformly one kind and can be either positive or negative. Use だらけ for things like 泥 or 傷 and ずくめ for a run of good things; they are generally not interchangeable.
• まみれN1まみれ means 泥, 血, 汗, etc. caked all over the surface, or figuratively being mired in things like 借金 or 嘘; it is mostly negative and focuses on what sticks to and covers the surface rather than on uniformity. For attached substances like 泥 or 汗, use まみれ — it is not interchangeable with ずくめ.
• ぐるみN1ぐるみ means an entire group taking part together (家族ぐるみ) or the whole of something with its outer layer included (皮ぐるみ), and does not express 'uniformly all one kind'; ずくめ means everything is the same color or the same kind of thing, so the two are not interchangeable.
• っぽいN3っぽい means having a certain quality or leaning toward a certain shade, as 黒っぽい means 'blackish'; ずくめ means uniformly all, so 黒ずくめ means dressed in nothing but black. っぽい is colloquial and can also attach to adjectives and verbs; the two are not interchangeable.
• がちN3がち attaches to the ます-stem of a verb (its ます form with ます removed) or to certain nouns and means 'tend to / be prone to,' focusing on tendency and frequency and often used for undesirable things; ずくめ attaches only to nouns and means uniformly all, with either a positive or negative nuance. The two are not interchangeable.
• 気味N3気味 means 'slightly tending toward ~,' a mild degree often used for less-than-ideal states, and can attach to a verb's ます-form or to nouns; ずくめ means 'uniformly all,' a thorough degree, attaches only to nouns, and can be positive or negative. The two are not interchangeable.

だらけ means full of something, usually undesirable, and まみれ means smeared with a substance such as mud or sweat. ぐるみ means "including everything" (e.g. 家族ぐるみ), while っぽい, がち and 気味 express only a tendency or slight degree, in contrast to the totality of ずくめ.
