Our classic white bodies (also known as vests or onesies) come in the widest ranges of sizes from preemie to two years; they have been our staples for nearly 25 years and have clothed a whole generation of happy babies! They have a really large envelope neck so are easy for you to put on and off your little one, either from the bottom up or head down, whichever you find easier. We also have found that the short sleeves are perfect for all year round, as it is the main torso of your baby that needs to keep warm and these bodies are much easier to put on and off without long sleeves. You will be layering up with a babygro and cardigan or jumper anyway over the body to keep your baby's arms warm and in the summer you may just have the body or no body at all. The fabric is soft and washes beautifully for years and multiple babies.
