What is your MUMSIE size?


We are so glad you are here on our sizing page that means you must be close to getting yourself in a MUMSIE! 

Here are 3 easy steps to getting the right size... 

  1. Measure your hips are the widest part and find your size on our size chart.  
  2. Check each product page for detailed notes about size and fit for that particular style. 
  3. For pregnancy fit, please keep in mind each pregnancy carries differently and we cannot guarantee your mumsie will allow extended pregnancy wear. Our mumsies are designed so the side buttons/ zip on the hip area undo, to give you extra width and comfort. 
Make sure you check the sliding size scale on each product page, on how each product fits. 
Have a question about size? Ask us here and we'll get back to you as soon as we can.. and don't worry if they don't fit, we have super easy returns and exchanges.
But how do I use them? Click here to see more.
