Jenna Ortega Wears Oscar de la Renta on Colbert

Jenna Ortega turned heads in a scarlet Oscar de la Renta mosaic dress on The Late Show, proving fashion sometimes demands a little sacrifice.

When Jenna Ortega stepped onto The Late Show with Stephen Colbert on March 25, 2025, all eyes were on her showstopping Oscar de la Renta dress—and not just because it looked like a wearable masterpiece. The strapless Fall 2025 design, adorned with intricate glass mosaics, was so striking that even Colbert, no fashion critic, couldn’t ignore it.
