do you think these bikini bottoms are inappropriate for 15-16 year olds?

I bought a pair of bikinis when I was on holiday, (I tried them on) and I thought they fitted really well and I was really excited to buy them because I’ve never had a proper bikini that I really liked and was excited to wear, the bottoms look a little like the bottoms in the photo, I’m turning 16 in two months and I was just wondering on your opinions on them as if you think they don’t cover enough bum, I really liked the style of bikini before I bought them and my friends think it looks really nice on me, I was just curious on all your opinions on these types of bottoms on teenagers
