I think there's a problem with that. The post says, "According to the San Bernardino County Sheriffs Office..." but that is not the description given by the SBCSO.
Every report including the Sheriff's office and RT himself says she was wearing a black bikini. I think this Facebook post is wrong.
July 17th - The search for Barbara Thomas, age 69, is continuing in the area of Kelbaker/ Hidden ... from SBSD - Colorado River Sheriffs Department : Nixle
Barbara was last seen wearing a black bikini, a red baseball cap and tan hiking boots with black socks.
I agree that it's unusual that this is the only source that mentions "shorts". However, I would have to believe she was wearing more than a two piece bikini. MOO
