How to prevent identity theft and better protect your family

Find out how to help you and your family overcome identity theft and prevent you and your child from becoming a victim in the future.

How to dress like an old man for 100th day of school?

Supplies for Costume.
NYX jumbo eye pencil (cottage cheese) for the mustache and eyebrows..
Baby powder for the hair..
Children's sunglasses or non-prescription glasses (I popped out the lenses for the sunglasses..
Suspenders..
Dress socks..
Khakis..
School uniform top..
Slip on shoes..

How to dress a boy as an old person?

Try khaki slacks, a sweater vest, and bow tie to go as an old man..
Wearing a full suit is another option, if you have one. You could also check a second hand store for a vintage suit..
If you want to look like an old man in pajamas, wear a matching pajama set with a robe and slippers..

How do you make a dress look old?

Wash your clothing in the washing machine using a regular cycle and hot water. Allow the clothing to air-dry outside in the sun to further fade them. You may have to repeat this process a few times before you get the desired effect. If you plan on cutting or ripping your clothing, do that first.
