Worst size inconsistencies I've ever seen. Beware
For anyone wondering if this is still an issue (I'm seeing posts about this from YEARS ago), yes - beware.
For reference, I am a Large in all t-shirts, dress-shirts, polos, etc. I ordered a linen long sleeve button up in a Large. The referenced size chart was pretty standard for my measurements.
What arrived was not the least bit correct. I was not able to be button up all the way without risking the integrity of the garment. It was AT LEAST a FULL size too small.
I exchanged for one size up thinking it would fit better. The XL that arrived was extremely baggy in every single possible area. Now AT LEAST a FULL size too large over stated measurements.
Two attempts to order, both results wildly off from their stated size measurements. Fabric quality might be good but it seems to end there.
