Answer:
Possessive apostrophes in this sentence
The bridesmaids' dresses are all different.
Step-by-step explanation:
In this case, bridesmaids' is a plural possessive noun. This is a noun that represents more than one person, place, or thing and shows ownership.
Most English plural nouns end in "s" to show that there are more than one of that thing. In these cases we just add an apostrophe after the "s."
