Perfect Fit, Perfect Comfort: Thea J’s Approach to Sizing

At Thea J, we firmly believe that size is just a number. Our pajamas and loungewear are designed to be loose fitting for comfort. The amount of ease you prefer can be accommodated depending on the size you choose. That’s why we’ve adopted a number system of sizes ranging from 1 to 4, along with flat lay measurements to help you discover the ideal fit for yourself.

What is flat lay?

With flat lay, we place the garments on a flat surface and then take measurements that are provided on our size charts below.

How to determine your size from flat lay measurements?

There are 2 ways to do this:

  1. Take measurements of your favourite garments and compare and/or

  2. Take measurements from your body as laid out below and add to allow for ample ease and comfort
