If a character's legs are touching at the knees but their feet aren't touching, use knees together feet apart instead.
If a character's knees and toes are touching, but their calves and heels are apart, do not use legs_together. Pigeon-toed is likely the proper tag.
If a character's legs aren't entirely visible but appear to be together, use your best judgment when determining whether to use this tag. A good example of legs touching is Danbooru post #2620773.
