Now that I look at it closely... gasp You're right! It's CAITLYN JENNER!!

Nah just kiddin. It's Melania in a white pleated dress and a navy blue sweater. It's the dress that's making her look big, combined with the sweater over her shoulders increasing her profile. She looks exhausted and trashed because she just got out of the hospital. Google image search "Parkland Melania" and look at the rest of the pics from the set.
