At this point, we've attended our fair share of fancy gatherings [1]: weddings, bridal showers, really elaborate birthday parties, etc. And while we've never had too much trouble finding the perfect ensemble — thanks to both celebrity and blogger outfit inspiration [2] — it did require a bit of effort, as well as a chunk of our paycheck.

That's exactly why we were so excited when we found out where Alexandra Daddario shopped her crocheted LBD — that she then wore to a pre-Golden Globes bash [3], mind you. Surely, you'd assume the intricate design would cost a pretty penny, but the piece is actually from Forever 21 and rings in at a jaw-dropping $30.

Read on to see her stunning look in full, then shop the affordable dress for yourself. You might want to rush: a red carpet secret this good definitely won't stay secret for long.

Alexandra looked stunning — and right on trend! — in this black crocheted design.

The affordable Forever 21 dress also featured a cap sleeve, which the star showed off as she posed with Kelly Klein.
