Old Navy is one of those shops that I can go for a long period of time without finding anything I like and then I will find some pieces to supplement my wardrobe with. Although I prefer their sister companies, they provide inexpensive casual items. I am not particularly impressed with their sales or clearance since they tend to be steep for the quality and slim pickings.
The staff are helpful and approach often in case you are lost or need to find something quickly. I was approached three different times while browsing. On most visits, I leave empty handed. Today, I was successful in finding a pair of shorts. Now if only Vegas weather would make up it's mind...
