In the first bra, there's a seamless layer at the bottom right here and it brings that nice touch because it's a different color.and you can't tell it's there or feel that it's there because it's that's how soft it is!
  
It's really thick on the back. There are actually four levels to it to where you can buckle it and it is very comfortable. This is probably one of the most comfortable bras that I ever had! Sometimes my bra straps would fall off my shoulders,but this bras won't, which is why I really love this.
  
 
these and so the second bra that they sent me this is more so a sports bra and it's like a light gray and pink. So the back of it as you all can see it's similar to the last one but I think it's more like tight, but won't be too tight and my chest feels really secure.
