With a refreshing white T-shirt, you can easily unbutton the sleeves to wear it as a sleeveless T-shirt for beach or outdoor locations, matching the setting. You can enjoy different fashions, so I think it will be an interesting item~ It's comfortable to wear, and if you wear it for a short time this year, you can wear it for many years to come, next year and the year after~ With the W chain necklace, I think it will attract attention with good balance~ The size is approximately 57 cm chest circumference under the armpits and 72 cm length when laid flat~ It is not a "bajack" (likely a typo or slang, meaning it's not a specific brand or style that is overly casual/sloppy).
