Chunky Heels
It is fine to wear chunky heels if you are going to a black-tie event. In fact, they will look perfect during those occasions. Outside of that, however, they will only look outdated. When you need to wear heels, it is usually much easier to look good in a point heel. This still is going to make you appear lighter.
Silk Scarves
You should not wear silk scarves to try and hide your neck wrinkles and lines. These things are only going to draw the eyes of others to that part of the body. On top of that, it is going to add the illusion of a heavy upper half. We are sure that this is not a problem that you want to deal with!
