There's a great upscale resale shop over next to La Vista restaurant on Fountain View between San felipe and westheimer. It's called "Second Childhood.
They are having a sale right now, they have sales a few times a year.
Last time I was there they had beautiful smocked clothes and a pottery barn dollhouse for sale!
"Now through Sat. the 16th we have a 20%off sale on all clothing and shoes. This sale also includes the brand-new things which have already been marked down half or more."
