Amazon EssentialsWomen's Slim-Fit Short-Sleeve Crewneck T-Shirt, Pack of 2

Are the white shirts see through?

I’m 5’6 and weigh 170 what size sounds good ?

In the hot pink/navy combo, the hot pink looks orange or coral. is it really pink tho?

What is the length of a small shirt? i see the picture measurements for the xs.
