Denim western shirt with short sleeves - LEVI'S

I've scored this low so buyers can take notice and be aware of my experience with sizing inconsistency's . The shirt quality is really really good and I've previously bought the long sleeved version of this shirt which is perfect. However the sizing I ordered 'Large' which is my usual Levi size was so so small I couldn't fasten the buttons properly . I exchanged for a' Extra large; thinking the sizing must be smaller on this shirt and it was too baggy . My conclusion is that the wrong label has been sewn in to the first shirt and likely it was a medium. I did request to swap to another Large but I've been issued a refund instead which is disappointing as it was present . I'll hopefully wait till the spring summer collections are in the local store so I can try on before purchase . Left disappointed by this particular experience .
