I borrow "fancy" clothes from my sister-in-law and also my niece-in-law. I'm a jeans, polo shirt and tennis shoe person not a fancy clothes gal!
I also get a lot of clothes from the local consignment and thrift stores. Several churches run some, also the Kidney Foundation and The Junior League.

Most of the time I find like new clothing for pennies on the dollar. Most all my polos are Ralph Lauren and I never pay more than $2.50! To me, it's a game of quality clothing for a fraction of the price.

But, understandably, used clothing isn't for everyone. Once I launder the goods, then they are mine!

I applaud you for starting your search early! That's smart!
