How to Choose the Right Baby Dress: A Buying Guide
Fabric matters most for everyday wear. For dresses your baby will wear regularly, soft cotton and cotton-blend fabrics are the best choice. Cotton is breathable, gentle on sensitive skin, and easy to wash at 30 or 40 degrees. Avoid synthetic fabrics next to the skin for babies under 12 months, as these can cause irritation and overheating.
For special occasions, look for lined dresses. Tulle, satin, and chiffon dresses look stunning in photographs, but the key is whether the dress is properly lined. All of our occasion dresses at Itty Bitty are lined with a soft cotton layer, so your baby stays comfortable even during long ceremonies or celebrations.
Ease of dressing is underrated. Babies are not known for their patience when getting dressed. Look for dresses with envelope necklines, poppers at the back, or wide neck openings. Dresses with a snap-fastening body underneath are particularly practical for younger babies, as they keep the dress in place and make nappy changes much easier.
Buy one size up for special occasions. If you are buying a dress for a christening or birthday party that is still several weeks away, size up. Babies grow quickly, and a dress that fits perfectly today may be too small by the time the occasion arrives.
Baby Dress Size Guide
Use the table below to find the right size. If your baby is between sizes, always size up for comfort.
Size Label | Approximate Age | Weight | Height |
|---|---|---|---|
Newborn | 0–1 month | Up to 3.5 kg | Up to 56 cm |
0–3 Months | 1–3 months | 3.5–6 kg | 56–62 cm |
3–6 Months | 3–6 months | 6–7.5 kg | 62–68 cm |
6–9 Months | 6–9 months | 7.5–9 kg | 68–74 cm |
9–12 Months | 9–12 months | 9–10.5 kg | 74–80 cm |
12–18 Months | 12–18 months | 10.5–12 kg | 80–86 cm |
18–24 Months | 18–24 months | 12–14 kg | 86–92 cm |
If you are unsure about sizing for a specific dress, contact our team before ordering and we will advise based on your baby’s current measurements.
Baby Dresses by Occasion
Christening Dresses A christening is one of the most photographed days in a baby’s early life. Traditional christening gowns are typically ivory or white, with delicate embroidery, lace trim, or pearl embellishments.
Our christening collection includes both classic long gowns for a timeless look and shorter occasion dresses for babies who will be more comfortable in something less formal. Always choose a dress with a soft cotton lining and avoid anything with scratchy lace directly against the skin.
Wedding Guest Dresses Taking a baby to a wedding requires a dress that looks beautiful in photographs but is practical enough for a long day. Our wedding guest dresses feature tulle skirts, satin sashes, and embellished bodices in blush pink, champagne, ivory, and lilac. Look for a dress with a comfortable waistband and enough room in the skirt for your baby to sit and move freely.
Birthday Party Dresses A first or second birthday deserves a special dress. Our party dresses range from fun printed styles to more formal tulle and satin designs for milestone celebrations. For a first birthday photoshoot, our pearl-embellished and bow-detail dresses are particularly popular.
Everyday Baby Dresses Not every dress needs to be saved for a special occasion. Our everyday collection includes soft cotton dresses, jersey knit styles, and lightweight summer dresses that are comfortable enough for daily wear. These are machine washable at 30 degrees and are made to last through repeated washes without fading or losing their shape.
Summer Dresses For warm weather, lightweight fabrics and loose-fitting silhouettes are essential. Our summer baby dresses include cheesecloth styles, cotton broderie anglaise dresses, and sleeveless sundresses with adjustable straps. Pair with a sun hat and SPF 50 sunscreen for any time outdoors.
