“I measured my head before orderign and was right in the middle of size L at ~62cm. The visor arrived and I think it is true-to-size in that it is slightly larger than my head and I need to tie the bow a little tighter to get a good fit. I am loving that I can pop it on over my messy bun rather than having to retie my hair whenever I need to wear a hat. The fabric is a lovely crisp linen but does flop slightly. I will wear it the the black side up (works with more of my wardrobe) and would have loved there to be a solid dark colour underneather rather than cream/black stripe as I find the reflected light on the underside of brim increases visual glare. Would love for you to make one that was a solid black on one side and solid dark-olive green on the other (or similar) in future and maybe with slightly stronger interfacing in the brim to stop the slight flop (the band is great though and the bow is very functional and not too big). Brim width is fantastic and I am so glad that you make larger sizes. Keep it up!”
