It doesn’t take rocket science… it just takes a soft tape measure (or a phone charger cord!)


We simplified sizing!

OOMLA makes products through puberty and beyond, so no one sizing system makes sense. We can't use a standard youth size chart for our adult-sized customers, and for our bras, we can't use the number + letter system (where the number is the rib cage size and the letter is the cup size) for people who don't fit into cups! And there was no way we were were going to use words like small, medium, and large because they're weirdly judgey... plus they mean absolutely nothing when it comes to our products. 

Want to buy an OOMBRA and need to figure out your size?

Your OOMBRA size = the number of inches around your chest measured at the biggest part of your boobs. To get your sizing right:

👁 Find the right spot to measure, which is where the nipples are (it's called the "nipple line").

📏 Wrap a measuring tape around at the nipple line, trying to keep the tape at the same level on the back and front sides.

🤔 No measuring tape? Use anything that wraps easily, so long as it doesn't stretch (phone charging cords work great!), then measure the using a ruler.

🚫 Don’t pull tight!! Boobs need room to be comfy.

⬆️ Always size up! OOMBRA sizes are a range of measurements. So, for instance, a 30-32 fits anyone measuring anything between 30-32. A person who measures 32 should choose OOMBRA size 32-34. When on the cusp between sizes, choose the bigger size for sure!

Want to convert your bra size into an OOMBRA size? 

You can convert your bra size to an OOMBRA size without measuring. Just find your bra size (number + letter) in one of the squares below. Then look at the color of each square. The OOMBRA color key below the chart shows your OOMBRA size.

BIG NOTE: Even though OOMBRAs only rely upon one measurement for sizing, some people have a bigger rib cages where he bra band sits, especially when boobs first start to grow. So if you're into measuring, feel free to measure that spot too, and go with the bigger number for your OOMBRA size!

How our prints affect fit

An important note about our prints and OOMBRA fit: Our super soft fabrics have natural cotton fibers that take dyes differently depending upon the color. Sometimes, darker or deeper color prints will feel tighter when they are put on, even though they will be super soft to the touch. It's weird, we know! But if you're on the fence between two sizes and you are choosing an OOMBRA with a darker or richer color scheme, we definitely recommend sizing up. 



To find the OOMSHORTS size that's right for you...

1. Decide where you're going to wear your OOMSHORTS: Do you prefer your shorts up on the waist or low on the hips?

2. Then measure that spot on your body using a soft tape measure* wrapped around.

3. Check out our sizing chart to match your OOMSHORTS size with the measurement.

Or, just do it the easy way and look for the size you normally wear on the chart!

OOMSOCKS fit kids and adults, all the way down to youth shoe size 1 and up to women's and men's size 12. To find the OOMSOCK size that’s right for you, check out the chart below. Just find your shoe size in one of the squares and you’r OOMsize will be listed to the left.

*Don't have a tape measure? Use anything with zero stretch - a phone charging cord works great! - wrap it around your body at the spot where the elastic band of the shorts will sit (waist or hips, you choose), then mark the spot where the two ends meet and lay it on a flat surface to measure the length against a ruler.
