To trigger place the file name in your prompt between to underscores.
Basic Clothing - Wildcard files for tops, bottoms, dresses, hats, shoes, outerwear, and accessories plus one file with full outfits. Mix and match them together in any combination to add variation to your images. Example prompt: 1girl, (wearing __dresses__, __footwear__), with a __accessories__, (long blonde hair, red lips), white background, full body shot
Newest Sporty Outfits - This wildcard contains a selection of athletic related clothing.
Clothing Style Only - Specifies a style of clothing rather than specific clothing items.
Fabric patterns and types -This one is really fun and mixes well with both my Basic Clothing file and with most other people's clothing wildcards to give clothing more variety and less boring solid colors.
Socks, Necklines, and Sleeves - Control individual parts of the clothing and/or give your character socks because if you don't specify socks, SD will make your character wear shoes without socks.
Style and Fit - This style file contains adjectives that affect the style of clothing and should be used with another clothing file (or you could specify what kind of clothing yourself), but is not designed to stand alone. The same with the Fit file. It controls how the clothing fits the character, (baggy, tight, tailored, etc), but doesn't work alone. You'll also find files here for clothing transparency and clothing details (to add things like pockets and zippers).
