About This Mod

The Flash Costume (DC’s The Flash 2023) is inspired by the movie version of Barry Allen’s suit. This full-body outfit has metallic red textures, glowing lightning accents, gold detailing, and the iconic chest emblem pulled from the 2023 film design. You’ll also find a mask to complete the superhero look. Note that this set is compatible with the base game, which means you can add it to your superhero collection without extra packs.

How to Install

Follow these steps to install The Flash Costume on your Sims 4 game:
