Im 5"0 and usually a size 0 in Lulu. This was my first purchase from firmabs and I couldn't be happier with how they fit and how comfy they are! I weight train so I was able to put them to the test. They are super lightweight and feel "cool" to wear. I didnt sweat hardly at all in these and they're also super soft! Would 10/10 recommend and will be purchasing another pair ASAP!
