See the big hole in Prince Harry's shoe at his best friend's wedding

The royal couple stepped out over the weekend at a close friend's wedding, and naturally all eyes were on them - as they have been since they tied the knot less than 3 months ago. 

Prince Harry and Meghan, Duchess of Sussex, attended the wedding of the prince's childhood best friend, Charlie van Straubenzee, to Daisy Jenks on the duchess' 37th birthday on August 4. 

The couple celebrated their own nuptials on May 19, in a lavish ceremony at St George's chapel in Windsor Castle. The press has been reporting on their every move, and the former American actress' every outfit, since their engagement was announced in November. 

Now, even at someone else's wedding, the couple were the center of the press' attention. 

The Duchess of Sussex stepped out in a Club Monaco colorblock dress wih a black button-up top, and sections of khaki green, baby pink, and white down the pleated skirt. The hemline fell down to mid-calf, and she had tied the waist with a black leather belt. 

She wore a pair of black pointed-toe slingback heels, a black fascinator, and a pair of dark round sunglasses. She carried a small black clutch purse. 

At one point, she suffered what many are dubbing as a "wardrobe malfunction" when a small portion of what could be either a lacy shirt under her dress or a bra appeared to slip out for a brief moment. 

An inch of the black lacy fabric could be seen in one of the photos snapped from the occasion. 

But it is a small detail of her husband's outfit that has become the center of attention. The prince looked dapper in a pair of light grey pinstriped pants, a royal blue double-breasted waistcoat, and a long black tailcoat. 

A guest noticed that underneath one of the prince's black dress shoes was a hole. 

It's not the first time the prince has stepped out in these, wearing them back in April. 

While some people in particular wondered when it became alright for royalty to sink to having holes in their shoes, others thought it was strange that something as small as a hole in the shoe is important.
