Mariann Marlowe’s popular boutique, Enz’s Rockabilly store, was one of many businesses hard hit by the 2nd Avenue disaster. It looks like it could be shuttered for two months or more. An online fundraising campaign has raised nearly $10,000. For the next week, Enz’s will be operating a pop-up shot at 103 Allen St., a space run by Made in the LES. You can stop by between 10 a.m.-10 p.m.
