Details:
For girls who have a small core/waist area but a larger chest/back/shoulders so the shirt is stretched at the top of their upper body but get loose at the abs and core her shirt for example
I wish I had something to add but honestly just wanted to chime in and say I love this look. That's a perfect example!
I found another great example!
Nice find!
Not the most attractive imo but very nice shirt and upper bod
