Flaw??? Citizens Of Humanity Blue Casual Button Down Shirt

This blue casual button-down shirt from Citizens Of Humanity is a versatile addition to any wardrobe. Crafted with attention to detail, it offers a relaxed fit and a timeless style perfect for everyday wear. ‼️ the sleeves have a stitching on the same side. I also have another shirt withthe same thing but since I didn’t buy directly from the retailer I do not know if this is purposely done by the brand or was previously sewn?
