Celeb fashion brands

I see articles and pics and they say which brand/designer made the clothes a star is wearing

Dress by X
Scarf by Y
Shoes by Z
Suit by B
Tie by A
etc.

Do they have a press person put out a press release for this info? I don’t think it can big figured out in a lot of cases.

Yes.

If you’re connected to politics in any capacity, just do not under any circumstances hashtag the designers you’re wearing and then attack your critics on Instagram. Not only will you generate ugly media coverage, but you’ll lose the support of the designers.

Has more to do with being a mega-rich person who leeches off taxpayers while flaunting it than being “connected to politics in any capacity.”

To return to the OP … the link led to an article about Mandy Moore on a red carpet somewhere. The things she was wearing were given (or maybe lent) to her by the designers at no charge. In return, she tells everyone who those designers were. She’s aided in this task by every interviewer starting off with “Who are you wearing?” That’s how red carpets work.

To me, stuff like

sounds more like what you see in glossy fashion magazines accompanying photo shoots. So the mag’s stylist buys (or borrows) certain items and puts them on the star for certain photos. They know exactly what the star is wearing because they put those items on her/him.
