SIZE GUIDE

At OiOiOi the clothes you order for your baby should have the perfect fit. That's why all our items from different brands are re-sized before we put their label on. Because when you find a label with 0-3 months written on it, how big is this anway? The intervals between baby clothes in the first few years are always 6cm and the smallest size starts at 44 cm. We work in centimeter indications because that's the approximate length of your baby, which can be measured.

Are you buying baby clothes for the first time and are unsure what size a newborn baby needs? Most of our customers start with size 50 or 56, but we also have clothing sets for preemies. From week 34 of pregnancy, the gynecologist can help determine whether the baby is more likely to be bigger / longer or smaller / shorter. Provided the child is born around the calculated due date, of course.

Babies outgrow up to 7 clothing sizes in their first year. Precisely because you need a whole new wardrobe every 6-8 weeks, it is worth renting the clothes instead of stowing them away in the basement almost unused. With our bundle subscription you can change to the next size at any time and at no extra charge. Wear and tear is insured and delivery and returns are free. 

Why not just buy bigger clothing instead of upsizing so frequently? You certainly can, for certain items like cardigans and then just flip the sleeves. Whatever is worn on the body directly needs to be close enough to actually insulate and at the same time not too close so the baby can still move comfortably.
