Riders by Lee IndigoWomen's Easy Care ¾ Sleeve Woven Shirt

The amazon "size chart" says the women's xl is equivalent to usa size 8? is that accurate? thank you.

Shirt labeled s/p. does that mean small/petite? i need a small not petite.

Is this shirt a regular Misses sizing or is it a petite?

Are there buttons on the cuff?
