I like the photos in this article that show how to make what you have look appropriate for work. That way you get some double duty clothes that you can also wear when you are not at work. It’s all in how you combine them.
There are more tips for getting deals on clothes of any kind–some great ideas.
A friend of mine is head of a social work agency that depends on state funding and charitable contributions for its budget. They can’t afford to pay their staff very high salaries. When my friend tells her staff they should dress professionally at work they complain they don’t get paid enough for that. She tells them to get work appropriate clothes at GoodWill, etc. and says that they shoul look like they are at work not on their way to a picnic. So no halter tops, shorts, or low-cut tops.
I like the linked article because it shows how to use casual clothes to make a more professional look. Click title for link at the DigeratiLife.
