Another fan called the dress “awful,” as a third chimed in: “She is too little to be dressed and made up that way.”

FESTIVE PHOTOS
In addition to the photos featuring Penelope, Kourtney also shared snaps with other family members at the Kardashians' annual Christmas bash.
Kourtney posted a picture with her sisters, with Kendall, 26, opting for a classic black gown, Khloe, 37, shining in a silver slip dress and Kim, 41, donning a Balenciaga look.
The siblings' mom Kris Jenner, 66, and grandmother Mary Jo completed the family festivities.
BABY ON THE WAY?
Kourtney has been raising eyebrows in recent weeks by fueling rumors that she might be pregnant with Travis' baby.
The KUWTK alum sparked baby speculation earlier this month when she showed off a kitchen closet stuffed with her huge junk food collection.
She panned through the large closet situated in her $8.5million home, showing off a series of chips, cookies and candy from the brand Bussin Snacks.
After the pair confirmed their romance in February 2021, fans have noticed many clues that could point to a potential pregnancy.
Back in July, Kourtney shared photos of a peculiar snack of pickles, vegan butter, tangerines and sourdough bread.
This wasn't the first time she's made strange meal choices, as she previously indulged in a martini made of water.
The Poosh founder held the coup glass that was filled with small white flowers to flavor her non-alcoholic beverage.
Also over the summer, Kourtney was pictured eating sushi without fish, as she went for a vegetarian roll with avocado instead.
