Plain Neutral Colors
Plain black, brown, gray, or navy socks may not be extremely commonplace anymore in the world of fashion, but they are still a good choice when you are in a conservative or formal environment. Plain, over-the calf-socks that are a shade darker or lighter than your slacks or suit are perfectly suited for traditional, restrained workplaces or events.
White Socks
White socks typically only look good with athletic wear. Most other outfits do not work well with white socks, especially if they are thick and ankle length.
Plain Bright Colors
These socks are an excellent way to liven up a simple, yet classic outfit. By matching your socks to smaller items, such as a tie, sweater, or watch, you can make your entire outfit look coordinated and put-together. A simple, well made sock in a bright color can coordinate with a wide range of clothing styles, from formal suits and dress shoes to casual jeans and sneakers.
Argyle
Argyle is a classic diamond pattern that looks equally well in a variety of colors. Argyle is traditionally used for dress socks, so they often look nice with slacks or dress pants. A subtle pattern that is mostly neutrals with one bright accent looks particularly good with slacks and a sweater in the same color family.
Stripes
Striped socks are very versatile, depending on their colors. More somber shades add a hint of interest to a formal outfit, while bright shades are seen as fun and whimsical. The consistent pattern of striped socks makes them work well with both pants and shorts. Stripes are generally seen as being slightly more casual, so they pair nicely with khakis or denim.
Other Patterns
Paisley, polka dots, zig zags, plaid, and floral are all other common sock patterns. A patterned sock can still be formal if it is in subtle colors, while bright colors add a playful touch. Keep in mind that busy patterns look best when the rest of your clothing is solid colors.
Novelty Socks
Novelty socks often contain goofy prints of items such as pizza, cartoons, or animals. These socks are fun, but they typically are not appropriate for the workplace or formal events. They work best for casual events.
For those interested in creating their own models, once you know these basic guidelines and what is your target market, you should be able to create custom socks that will appeal to your potential customers.
