Classic Collar Organic Cotton Denim Button-Up Shirt

I ordered this shirt to match the pants that come in petite sizes. I am 5 foot size 4, athletic. If I were 5'3" this might fit. I ordered a small. Usually an XS is too small/tight in the shoulders and still too long in the arm and arm pit. Why not ALSO make this matching shirt in petite??? if one is petite usually a regular sized long sleeve is too long! while the small feels/looks good on my shoulders, the arms are long and it's a bit boxy in the body/under arm area and it just looks too big on me like i'm a shrinking woman...I pre ordered this so it took some time to arrive so now I am ordering an XS small for a try and hope that it fits better. It is a really nice material and I love this length- on me like a boyfriend shirt.... The pants too are really nice in PETITE small on me- lands on my ankle so even the pants sometimes are too long in petite but they fit. if you're of standard size and normally a small, this will look lovely on you. MORE quality PETITES long sleeve shirts PLEASE!
