YEXIPOGraphic Tees for Women Short Sleeve Summer Tops Funny Letter Printed Loose Casual T Shirts

Is this a women’s t-shirt size, or unisex (men’s sizing?)

I’m 5’4” 156lbs what size would I need?

Is this a boxy fit? Are the sleeves longer than a normal tee?

Are the yellow & orange "Bring on the Sunshine" shirts bright colors like lemon yellow, etc? Or are they more of a mustard yellow & burnt orange??
