Hanes Women's Cool DRI Performance V-Neck T-Shirt, Moisture-Wicking Short Sleeve Tee, 40+ UPF Protection

What size is The model wearing in these pictures? I would like this typo of fit. Im afraidthe small will fit snug

How how do I return shirts when packaging has been destroyed?

would it be tightly or loosley fit?

I have the black and the navy, and I like the high v neck. The grey colors look like the v may be a lot deeper. Is this the case?
