Rosablue Baby girl's birthday dresses
The 3D Butterfly dress — the dream come true
The 3D Butterfly dress is one of the most poetic and photographed creations in the Rosablue Baby collection. Hundreds of small embossed butterflies entirely cover the dress — on the voluminous puff sleeves, on the multi-layered flared skirt, everywhere. Sparkling crystals are integrated into the fabric to catch the light. Available in salmon peach pink and bright pink, this dress is ideal for a butterfly, garden, princess, or fairy-themed birthday. Your little girl will be absolutely unforgettable.

Available in multiple colors and different sizes, from baby to older child, it is designed to be comfortably worn for an entire day of celebration.

The Angel dress — two looks in one dress
The Angel dress is an absolutely signature Rosablue Baby creation. Bodice and sleeves entirely covered in golden sequins, detachable puff sleeves for two different looks, and a large satin bow at the back. Worn with sleeves: glamorous gala princess look. Without sleeves: elegant and modern cocktail look. This dress is perfect for the most festive birthdays, but also for christenings and formal weddings.

Important advice on material selection
At Rosablue Baby, we know that every child is different. Some little girls love the volume of tulle and spinning around all day. Others prefer something softer and lighter against their skin — and that's perfectly normal. If your child is not used to voluminous materials, we offer softer organza models, without superimposed tulle, which offer an elegant look and beautiful photos without any discomfort. Do not hesitate to ask us for advice.
