Knee Sleeves sizing help?

I want to get the strength shop 5mm knee sleeves but struggling with what size to get. I’ll list there sizing guide below:

Size Guideline: S - 30.5 - 33cm M - 33 - 35.5cm L - 35.5 - 38cm XL - 38 - 40.5cm XXL - 40.5 - 43cm

I measured where it asked for and I get 38cm which is L/XL. But I’m thinking what if I size down to M would that be too tight and I wouldn’t even be able to get it on?? Any advice?
