Though he was ousted from Men’s Wearhouse, George Zimmer still wants you to “like the way you look” — only this time with an app.

Once the gravelly voiced, graybeard face of the retail chain he founded, Mr. Zimmer has been refashioning himself as a technology entrepreneur. On Monday, he will unveil his new company, zTailors, a website and app that connects customers and their frumpy wardrobes with on-demand tailors who are ready to make house calls.

“It’s Uber for tailors,” Mr. Zimmer, 66, said in an interview.

Backing the nascent company with his own money, Mr. Zimmer says he believes that zTailors — yes, the “z” is for Zimmer — has the potential to transform millions of ill-fitting garments into like-new items.

Its app and website allow customers to schedule a tailor to come to their homes or offices, where they will measure and refit suits, shirts, jackets and dresses for a set price. The altered items are then returned in a few days.
