Nails are the CAS slot nobody thinks about until they zoom in. The base game gives you a handful of flat polish swatches painted onto the default hand mesh — no length, no shape, no art — so the moment you install a good skin overlay and a decent hair, the hands are the thing that still looks like 2014.
This collection is every Sims 4 nail set in our catalog in one grid: 145 finds, sorted by downloads. Shape is the thing most people filter for and it is well covered here — long stiletto, coffin and ballerina, almond, square, and the shorter natural sets for sims who are not supposed to look like they just left a salon. Around a dozen sets are built specifically around an aesthetic (y2k, goth, coquette), there is a small bench of french-tip and solid-polish packs for the ones you want to be invisible, and a handful of seasonal sets — Valentine's, Christmas, summer — that people swap in and out through the year.
The creators who show up most are the ones who basically only make nails: LVNDRCC has the biggest single shelf here, Feyona covers the fine, realistic end, and VICCS, WisteriaSims, VELYSEA, Joliebean and frenchiesimgirl fill in the everyday CAS sets. The single most-downloaded item in the grid is a striped Hello Kitty set, which tells you roughly everything about what this category is for.
Two practical notes. Nail CC is split between sets that live in the nail-polish slot and sets that ship as a glove or ring accessory to get the length — the accessory kind will fight with bracelets and with some gloves, and the usual symptom is one of them disappearing in-game. And long nails clip through a lot of animations and hand poses; if you are shooting screenshots with a pose pack, a shorter set almost always renders cleaner than the XL claws.
Everything in this grid is Sims 4 only, filtered to SFW, and checked for a working download link. Sort by downloads for the sets half the community already has installed, or scroll for the single-pack releases the big roundups never reach.
