Packing the Basics for a Long Weekend

On Friday I will be heading out for the weekend to attend my cousin's wedding.  The airline that I am flying with is the only carrier to fly direct to the destination. While it is convenient flying non-stop, the airline has lots of fees not included in the ticket price.  One such fee is for carry-on luggage, they charge you a flat fee each way for a carry-on bag.  I haven't flown in while, so maybe this is standard practice now.  Trying to save money and my back I decided to fit everything into one tote bag.  I brought mix matchable basics as well as the dress and shoes I am wearing to the wedding.  To give you an idea of what I brought I created a set of pieces (all under $100) that can be mixed and matched to create a multitude of looks to last a long weekend.  One of the outfits would be worn when traveling and can be reused in other looks.

What do you think? What do you pack when you are going away for a long weekend?
