Avenue is a store. Personally, I don't like them because I don't think their quality is that great. Clothes I had from them would fall apart after only a few uses.
I never had a problem with Avenue clothes. And I've been wearing them for as long as they have existed. They used to be/or bought out a store called 16 plus.....
Maybe I'm harder on my clothes or maybe I've had bad luck with Avenue I used to shop at the previous Avenue store too but it was called something else in California, not 16 plus. I've had pant seams split, zippers break, bras unravel, shirts unravel, hems unravel, etc. As opposed to clothes that I bought at other stores which never had those problems.
