We got our BM dresses at Nonchalance and luckily received them a few weeks ago. My sister was planning on doing her alterations there at Flair, but now they are closing too.
She called Hearts for You in Manalapan and they were so nice! Normally they don't do outside alterations but they are accommodating Nonchalance BMs. She said they are so nice and super helpful. Their number is 732-536-7808.
I feel so bad and hope this helps someone!
