Pastel Overload
The older people get, the less it is appropriate for them to dress in pastels. The explanation for this is fairly simple: they thoroughly wash you out of your skin. As previously said, our hair and complexion naturally become dull as we grow older, and wearing pale hues will further accentuate this impression. However, this does not rule out the possibility of wearing pastels in the future. All that is required is that you select them with care. Experiment with different hues and tints to see how they look against your complexion and hair, and then build on your findings.
Too Much At Once
If you prefer to dress in a more conservative manner, it is entirely your choice. However, if you feel as though you are looking older than you actually are, the explanation for this could be that you are wearing too many conservative components in one ensemble. Wearing tweed with pearls, for example, will immediately make the person wearing them appear older. To add a younger touch, try isolating those items and matching them with outfits that are more whimsical in their design. In the event that you nevertheless want to wear them together, make sure to incorporate a contemporary touch to maintain oneself appearing young and new.
