I didn't see any place in the article where her dress was described as a mini dress! Instead it was described below as follows
... It has bows on each strap, which are embellished with jewels and a fitted silhouette that hits a few inches below the knee...
It is in the headline:
Melania Trump Rocked a Black Dolce Gabbana MiniDress for New Years Eve.
Granted, the headline is quite possibly not written by the author of the article.
MiniDress is in the title. There are more snarks in the article which I edited down to bring it down to 300 words.
These are mainly pertaining to the hoopla made over designers refusing to dress her. Seriously, as if a high fashion gorgeous model like Melania with the perfect figure would ever be caught dead wearing some of their gaudy designs worn by Mooche.
