Translation guide
In Japanese, the word for 'accessory' depends on what kind of accessory you mean. Fashion accessories like jewelry, bags, and scarves are usually アクセサリー. Small decorative items attached to something (like phone straps or keychains) are often アクセサリ or 付属品. Accessories that are part of a machine or device are 付属品 or アクセサリー. For a person who assists or accompanies someone, use 付き添い or アクセサリー (metaphorically).
The most common meaning: items worn or carried to complement an outfit.

アクセサリー is the default for fashion items and is also used for device accessories in casual contexts. 付属品 is more technical and emphasizes that the item is attached or included with something. For small attachable items like phone charms, アクセサリ (without the long vowel) is common in product names.
This bag can also be used as an accessory.

While アクセサリー is versatile, using it for a person (as an attendant) can sound odd or metaphorical. For legal contexts, use 従犯. For machine parts, 付属品 is safer in formal writing.
