Quick answer
Choose a muslin shirt for hot days, a seersucker shirt for warm weather with a bit of texture, and a corduroy shirt for cooler months. Each fabric suits a different climate and activity level.
Muslin Shirt
Why fabric matters for baby shirts
Babies have sensitive skin and can't regulate body temperature as well as adults. The fabric of their shirt affects comfort, breathability, and ease of dressing. By choosing the right material, you help your baby stay happy and comfortable throughout the day.
When muslin works best
Muslin is a lightweight, loosely woven cotton fabric that allows maximum airflow. It's ideal for summer or hot climates. The Garbo&Friends Muslin Shirt (short-sleeved) is a great choice for keeping a baby cool while still offering coverage and a classic button-front look.
When seersucker is a good alternative
Seersucker has a puckered texture that creates tiny air pockets, helping it stay off the skin and reduce sweat. It's slightly more structured than muslin but still very breathable. The Garbo&Friends Seersucker Shirt is perfect for warm days when you want a bit more visual interest without sacrificing comfort.
When corduroy is the better choice
Corduroy is a thicker, soft-ribbed cotton fabric that provides warmth. The Garbo&Friends Micro Corduroy Long Sleeve Shirt is ideal for fall, spring, or air-conditioned rooms. Its long sleeves and soft texture make it a cozy option for cooler weather while still being easy to move in.
How to choose the right baby shirt fabric
- Check the weather: For temperatures above 75°F (24°C), choose a short-sleeved muslin or seersucker shirt. For cooler weather below 70°F (21°C), pick a long-sleeved corduroy shirt. Muslin and seersucker are warm-weather fabrics; corduroy is for cooler days.
- Consider activity level: If your baby is crawling or playing actively, seersucker's texture helps reduce sweat and cling. For quiet play or naps, muslin's softness is very comfortable.
- Think about layering: Muslin shirts layer easily under a cardigan or jacket. Corduroy shirts work well over a onesie or as a standalone top. Seersucker is less suited for layering but can be worn under a lightweight vest. Corduroy is the best layering piece for fall; muslin works under any layer.
- Check care instructions: All three fabrics are machine washable. Muslin may wrinkle more, while seersucker holds its shape. Corduroy needs gentle washing to preserve the nap. Seersucker requires the least ironing; corduroy needs more care in the wash.
