Princess Charlottehad quite a stylish weekend!

After a busy Saturday attending her grandfather King Charles’ first Trooping the Colour as monarch, Princess Charlotte joined her siblings,Prince GeorgeandPrince Louis, for a new portrait with dad Prince William to markFather’s Day.

In the adorable two photos (thefirst one, released on Saturday, showed the foursome giggling and asecond snapshowed them smiling for the camera like pros!), Charlotte was wearing one of her go-to summer dresses.

“It’s smart enough to go to a rehearsal at the Abbey and at the same time, it’s casual enough to work in a woodland setting having fun with your brothers and your dad,” Riley tells PEOPLE exclusively. “They all looked absolutely gorgeous; it’s such a fun photo!”

“It’s been a best-seller since I designed it 25 years ago! My daughter Rose [who is now 30 and works alongside her mom] wore the same dress when she was little, and it remains a best-seller today,” says Riley, whose business went online and wholesale just recently during the COVID-19 pandemic.
