We had to always shop the sales racks for clothes. Sometimes you could go into a nice store and find a clearance rack where things had been marked down multiple times. You didn't get the greatest selection, but some of the stuff was decent. I still use this trick today to round out my wardrobe.
What I felt like I never had enough of was shoes. My dad believed that you got one pair of dress shoes for summer and one pair for winter. Then, you got one pair of athletic shoes and a separate pair of sturdy school shoes. No cute little girl flats or other cute shoes that a girl might like. I feel like if we didn't have to spend money on dress shoes that I could have had decent shoes for everyday.
I had it better than my sister, though, who got stuck with a lot of my hand-me-downs. I remember one time getting a box of hand-me-downs from a family at the hall and that's the only time.
Now once my baby brother was the only one left at home, they could afford to buy him pretty much what he wanted.
