This was a picture I took of a Christmas gift for my youngest granddaughter. It highlights the improper use of an apostrophe. What exactly belongs to Barbie? Or are you talking about more than one Barbie? Perhaps you’re talking about 20 Barbies? If this had said 20 Barbies and Barbie’s accessories, then the apostrophe in the second “Barbie” would be correct because you’re talking about accessories belonging to Barbie. As it is here, the apostrophe is incorrect because you’re talking about 20 Barbies so it is plural NOT possessive.
