No clue. Looked over Yelp and there’s only 5 reviews and StyleForum seems to be pretty empty.
I really, really don’t like the idea of buying a flash-sale tailoring deal. Sure, it’s a “bargain”, however, unless you have a prior relationship with that tailor and know he’s great, why would you put down ~$500 into such an unknown transaction? You’re acting out of blindness without even having had a conversation with the tailor or know anything about his work.
I’d rather pay twice as much and know what I’m getting instead of half as much and later regret it. Just my thoughts.
