... but it may not be the de la Renta who first comes to mind.
A few weeks ago we posted about this red mystery dress - a crowd pleaser that the first lady has worn at least twice in recent months, but also one for which the designer has proven difficult to identify.
We've learned that the dress is MDLR, a new, young label led by Moises de la Renta, Oscar de la Renta's son. The dress is a one-of-a-kind piece made especially for Mrs. Obama and constructed from Gandini sponge crepe.
We can rest a bit easier knowing who is behind this fabulous frock - and what a fantastic twist in the story of Mrs. O's fashion.
