Spoiler Alert…Supergirl was spotted swapping her iconic superhero costume for a pretty pink dress as she attended THE Wedding of Barry Allen AKA The Flash and Iris West!

Melissa Benoist AKA Supergirl AKA Kara Zor-El was joined by Alex Danvers, played by Chyler Leigh, outside the steps of St. Paul’s Lutheran Church.
Supergirl / Kara Zor-El matched her glittering silver crystal with red lipstick, black framed sunglasses, and a matching pink sparkly clutch handbag.
Chyler Leigh and Supergirl were filming scenes for a Supergirl / The Flash cross-over where Barry Allen is set to get married to Iris West.

Chyler Leigh fashioned a see-through elegant dress as she looked to be arguing with Supergirl outside the clutch.
