Finding Your Measurements
The chest dimension is your chest size.
- Wrap the tape measure under your armpits, around the fullest part of your chest.
- The tape measure should be snug. Not so tight that it constricts breathing, but not so loose that the tape measure slides down.
- Don't puff out or flex your chest, just stand normally.
WAIST SIZE
The waist dimension is your waist size.
How to measure your waist:
- Wrap the tape measure around your natural waistline, between your belly button and the bottom of your rib cage (if you bend to the side, the crease that forms is your natural waistline).
- Don't suck in your stomach, just stand normally.

Super cute, super fast shipping!
My sister loves her shirt. As a future nurse, I suggested that she could use it to study for her anatomy classes ;)

Sooooooooft
Bought a size up, L instead of M. Fits great, not loose, not tight. The material though....oooooooh, so incredibly soft. I’m definitely checking out a few others.

Anatomical Heart Graphic Tee
GIFT FOR MY GRANDDAUGHTER - an EMT/Paramedic Student. She LOVES it! Many thanks. True colour, great fit.

Anatomical Heart Graphic Tee
This was a Christmas gift for my granddaughter. She is an EMT and a Paramedic student. She LOVES it. Thank you.

Cute cut, excellent quality, cool design
Got the women's XS for a 13yo scientist and she loves it. This is my second tee from Cognitive Surplus. The first one is nearly a year old and holding up beautifully.
A great fit! A fun shirt!!
I really love the shirt. I work in a pediatric cardiac ICU and got so many complements especially for heart month but when I washed it the stitching came out around collar. I washed on cold and hung to dry. I have reached out to company so hopefully it’s just a fluke and replacement will be fine. Never shrunk and material feels good. Red maroon color pretty also
Amazing
I just received this shirt and I am beyond impressed!! Super soft and looks amazing, plus it’s great quality I definitely recommend this 100 times over. I am in love and will definitely be ordering again.
These glasses are beautiful. However, after using them for a week or two the print is already starting to fade... and because they were shipped in a slightly weird way, I had to pay an additional €30 of taxes when they arrived in Germany. So 50-50!
The shirt is very soft. Love the fit. I wear xs-small and the small fits well. My friend (a nurse) to whom I gifted a matching one loves hers, too. Thanks!!
