Seamstress/Tailor for Alterations?? **Repost from BHB**

I am the Maid of Honor in my friends wedding in September and I am in desperate need of getting my dress altered! Does anyone have an recommendations for a great person who can do the alterations?? And not have it cost an arm and leg (like my wedding dress is going to)
Some one preferably in Nassau (best if South Shore but I will travel to North Shore or western Suffolk)

TIA!!!!!
