An increase in adaptedness doesn't necessarily mean an increase in fitness?

An adaptation refers to a characteristic that benefits an organism in a particular environment, while fitness refers to an organism's ability to reproduce, correct? Therefore, some acquired traits may allow for an individual to survive better in the environment (camouflage), but decrease their sexual appeal (decrease in fitness, since they won't reproduce as often.) Is the original statement a correct assumption, or have I made errors in this paragraph?An increase in adaptedness doesn't necessarily mean an increase in fitness?That may be possible, but "fitness" is one of those things that is determined after the fact - in this case, fitness would be measured by the number of offspring which survived to reproduce themselves. As a general rule, one would expect an "increased adaptedness" (however you would define it) to result in increased "fitness", although I suppose it could work against it.
