What to Look for in Baby Girl Clothes
Choosing the right baby girl clothes involves balancing style with practicality. Babies need clothes that are soft against sensitive skin, easy to put on and take off, and durable enough to survive repeated washing. Here is what to consider when shopping for baby girl clothing.
Fabric is the most important factor. For everyday wear, soft cotton and cotton-blend fabrics are the best choice. They are breathable, gentle on sensitive skin, and machine washable at 30 or 40 degrees. For occasion wear, look for dresses and sets that use tulle or satin overlays lined with a soft cotton layer — this gives you the beautiful look of occasion wear without the discomfort of scratchy fabric against the skin.
Ease of dressing matters more than you think. Babies are not patient when getting dressed. Look for clothes with envelope necklines, poppers at the back or crotch, or wide neck openings. Sets with a bodysuit base are particularly practical for younger babies, as they keep the outfit in place and make nappy changes much easier.
Buy one size up for special occasions. If you are buying an outfit for an event that is still several weeks away, size up. Babies grow quickly, and a dress or set that fits perfectly today may be too small by the time the occasion arrives. Our size guide covers newborn through to 24 months with weight and height measurements for each size.
