A lot can be said for a solid sock in a bold color. Once it gets busy with a lot of stripes, designs or polka dots, it can get distracting and take you from modern to messy. If you are not sure, I suggest stick to a classic and simple sock choice in a bold color. Personally, I have made my go to sock a nice cherry red. I put it with everything and just say it matches. Because it is a primary color, it tends to be bold without contrasting from most outfits. Dont like red? Thats fine. Find something you like and try it out. If it doesnt work, try something else. Luckily socks tend to be an inexpensive way to have fun with an outfit. An easy way to mix and match is to go withUniQlosolid socks priced at an easy to obtain four for $12.90.
