Flutter Sleeve Traditional Dress for Communions

Dody Lacle

Very happy with the dress

Dear Miabambina

I am very happy with the dress, it came out stunning. My daughter was very happy with her dress. The fabric was gorgeous and very well made. I would totally recommend and would buy again.

Christina-Long-Sleeved First Communion Dress

Guerlane Bernadel (Freeport, US)

Absolutely Gorgeous

This dress is absolutely stunning in person — photos simply don’t capture its true beauty and intricate details. The craftsmanship and design took our breath away, and my daughter received endless compliments. Our family and friends were amazed by how beautiful the dress was. I’m so glad I chose the custom sizing option; it fit my petite daughter perfectly. I can’t thank you enough for the exceptional dress, outstanding customer service, and excellent quality. I was pleasantly surprised to even receive a garment bag with the dress. Thank you again — I will happily recommend you to everyone and look forward to being a returning customer!

Andromeda Sophisticated Communion Dress with sweetheart neckline

Rachel M (East Gwillimbury, CA)

Like a princess

This dress was even more beautiful in person! The detailing and the fabric is incredible. Cimes with a hoop skirt underneath tp allow the dress to stay poofed out. Our daughter will look perfect on her communion day thanks to Mia Bambina!
