Was it just us or did Kate Middleton's dress at Meghan Markle and Prince Harry's royal wedding look very familiar? That's probably because we thought it was a recycled outfit — but apparently we were wrong about the Duchess of Cambridge's frock.

It would appear one astute fan, Royal Addicted, has realized that it wasn't the same outfit. They may be strikingly similar, and both by Alexander McQueen, but Kate did in fact wear a different dress to her brother-in-law's wedding last month. The new dress was actually a primrose yellow, not cream, and unlike the original frock, the new one had a row of four buttons on the cuffs.

For the nuptials on Saturday, May 19, Kate wore what we thought was her off-white Alexander McQueen coat dress, even though it turned out to be the primose yellow one. She paired the look with a fascinator of the same color, adorned with big white roses. She also donned a pair of nude pumps. The 36-year-old looked especially stunning in the ensemble considering she gave birth to baby No. 3 less than a month ago at that time!

Kate previously sported a similar look for her now-three-year-old daughter Princess Charlotte's christening in July 2015, which is why we thought it was a recycled outfit. On that day, Kate paired the dress with a similar fascinator adorned with flowers and a pair of nude pumps. For that look, though, she wore her hair in a low side bun, unlike the wedding, where her tresses were down.

But that wasn't the only time Kate wore the off-white number. The mom-of-three also donned it to the 100th anniversary of the Battle of Passchendaele in Belgium in July 2017, but that time she paired the outfit with a pair of gray pumps.

Kate also wore the ensemble for the Trooping the Colour back in 2016. She waved on the balcony of Buckingham Palace with Princess Charlotte in her hand, but that time around, she wore a pink fascinator to go with the off-white dress.

Each time Kate wears the Alexander McQueen numbers she looks equally as stunning — but are you convinced she wore a new outfit for Meghan and Harry's wedding?
