In The Sims 4 , custom content generally falls into two categories: standalone items and default replacements.
In the world of Sims modding, a "Default Replacement" (DR) is a file that overrides the game’s original files. Unlike "Non-Default" CC, which adds a new item to your catalog, a default replacement swaps the existing base game underwear for something else.
If you use the High-Quality (HQ) texture mod, ensure the underwear texturing supports 4K resolutions to prevent blurring.
By installing a default replacement, you upgrade every male Sim in every save file—from your legacy founder to that random townie jogging past your lot—without having to manually edit anyone.

Popular choices in this category often feature upgraded boxer briefs with realistic waistbands, improved mesh definitions, and a wider variety of neutral or vibrant color swatches. 2. Alpha CC (Hyper-Realism)
Alpha replacements focus on high-definition photorealism. These mods introduce detailed fabric textures (like cotton, silk, or athletic mesh), realistic folds, shadows, and anatomical definition. Creators like Golyhawhaw and David Sims have historically been staple names for players seeking to elevate their male Sims with sharp, modern, and highly detailed undergarments.
