How OiOiOi works

The choice is yours! Our rental plans with 5 - 20 clothing items are available on a monthly basis, with only 1 month notice period for flexible cancellation or you can go for a worry-free package with our yearly subscription and profit from a discounted price.

Here is how it works:
1. Pick your plan (size of your bundle). Pay monthly or yearly.
2. Choose your child's clothes and fill your bundle.
3. Wear. Normal wear & tear is insured, free delivery & return.
4. Swap. Change size anytime or do a bundle refresh from size 80 onwards every 3 months.

When to start a subscription

It's recommended to start your subscription before your baby is born, so we can plan your clothes ahead. You sign up for your subscription anytime, the first month's payment will be deducted at purchase. If you order a starting size of 44, 50 or 56 (newborn sizes), you will receive a link to select your items one month before your entered due date. Your subscription fee will start only at the entered due date, so the second payment will be deferred.

(Sometimes it happens that your credit card get's charged for the months before the official start of your subscription. This amount will be automatically reembursed 2-3 weeks later. This is a technical issue and we're working to fix this for you!)


For the monthly plans, the minimum subscription period is one month. After one month, you can cancel your subscription anytime in your member profile to the next payment cycle. All clothes need to be returned and arrive at OiOiOi 5 days before the cancellation date for the notice to take effect, or the subscription will be extended by another month.

The yearly plans have a fixed expiration deadline. All items need to be returned and arrive at OiOiOi 5 days before that expiration deadline. If the bundle is not returned 5 days before the expiration deadline, a monthly subscription will be charged thereafter.

You can cancel your subscription and see your payment cycle in the member area.

Bundle content

You can fill your bundle with items you like. Please note that one subscription is meant to serve one baby, so there are certain product limitations which you will see when filling your bundle. For instance, only one overall per subscription is allowed, to ensure there is enough for all OiOiOi babies. The community thanks you for respecting this!

Changing size

Please login to your member area for switching size. You can also change your profile and manage your subscription from there.

Mixing sizes

We advise that all of the items in your bundle have the same size, because we are resizing all of our brands' items before they are uploaded into the shop - exactly, so you don't have to do this and everything fits. We do provide replacements for clothes that don't fit, but cannot guarantee this if you are mixing sizes in your bundle.


The clothes in your bundle should fit your baby. All our clothes from different brands and sizing methodologies have been resized by OiOiOi so they correspond to a standard size in centimeters. Should an item be too small or faulty, you can request a replacement item. Replacements can only be guaranteed if you choose the same size for all of your bundled items.

Log-in to the member area and request our staff to pick an alternative item for you.

Upgrade or Downgrade

You can upgrade or downgrade your subscription at every size change. The next monthly charge will be adapted according to your newly selected plan. There are no refunds inbetween payment cycles.

Partial return

Bundled items should always be shipped together, as a bundle. Even if you have some items from the bundle that still fit, all items must be returned. This way, we reduce shipping emissions and you can refresh your wardrobe every time you swap your bundle.

Should you have forgotten to return something, you can send it separately to this address:


Warentor 3

Industriestrasse 3
