Does anyone know...

of a good place to get a wedding dress in Suffolk?

...Besides Macy's. Thats the only place I have been in LI so far.

I have friends that have had luck at:
Paradise Bridal, Patchogue
Adrienne's, Islip
Burton's, Melville
Centereach Bridal

Sure, there are lots of places!! I got mine from Paradise Bridal in Patchogue. There's also the Bridal Suite of Bayshore, the Bridal Suite of Centereach, Helen's Bridal in Commack, and Estelle's; just to name a few. There are plenty of others but I can't think right now!
