The specialty women’s clothing retailer’s IPO – which isn’t its first – of 11.67 million shares is expected to be priced between $14 and $16 and could generate about $150 million, valuing the company from $750 million to $800 million. The Quincy, Mass.-based retailer, which caters to the college-educated woman from 40 to 65, touts itself on having a “passionately devoted customer base,” as 70% of its 2015 gross sales came from people who had shopped at J.Jill for at least five years.
