Queen's Diamond Jubilee: Are Princesses Beatrice And Eugenie Making A Fashion Comeback?

Princesses Beatrice and Eugenie have not always been known for their style.

Beatrice donned the infamous "world's worst hat" to Will and Kate's wedding, and Eugenie has made some, um, less than stellar sartorial choices over the years.

But it looks like their fashion fates may be on the upswing.

Today, the princesses were spotted donning perfect-for-summer frocks at the Queen's Thanksgiving Service at St. Paul's Cathedral. And, we have to say, they look remarkably on trend and event appropriate. There's nary a wardrobe faux pas in sight!

Princess Eugenie paired a plum satin dress topped with a floral-embellished Stephen Jones beret, and Princess Beatrice donned a fascinator with a periwinkle coat by Kinder Aggugini.

What do you think of their ensembles?
