babyshower dress

Angie 🌻
Hello Ladies, 
My babyshower is on Aug 4 and I have yet to find my dress. I see all these beautiful posts on IG but I am so afraid to order and have issues with delivery and size (making sure it fits). Do any of you beautiful ladies know of a good store? I am in New York. My babyshower theme will be ballerina princess and I will like to wear white, light pink or white and silver. 
Please help. 
Thanks 💕
