Let's make this birthday one to remember.

51 years old (Born on April 21, 1974)

Happy Birthday, Jeffrey Costello! Another year of fabulous designs and impeccable style—clearly you're aging like fine fabric. From runway triumphs to redefining fashion with your partner-in-crime Robert Tagliapietra, you've stitched together a legacy that's both timeless and trendsetting.

Whether it's crafting iconic dresses or charming the industry with that legendary beard-and-suspenders combo, you always keep us inspired (and slightly jealous). Here's hoping this birthday is as vibrant as your latest collection—and filled with laughter louder than backstage chaos at Fashion Week!

Cheers to another stylish spin around the sun; may it be tailored perfectly just for you!
