In card games, sometimes you have to play a card from the same suit as the previous player. For example, if someone else just played a heart, you have to play a heart, too. When you do, you're following suit.
And more generally, to follow suit is to do the same thing as other people are doing. For example, if you hear a strange melody, and you see all your friends get up and run toward the sound, then even if you don't know what's going on, you'll probably follow suit: meaning, you'll do the same thing that your friends just did.
Finally, when something suits you, or suits you well, it's suitable for you, which means it makes you look good, it makes you happy, or it gives you everything you need. Just like a suit is a full set of clothing that fits you very well, anything that suits you, or suits the situation, is fitting and appropriate: it'll work, it's helpful, and you like it. For example, if you have a nice, flat desk and a bright light, then you have a suitable place to do your homework.
If you're going to the pool, and you want to keep the sun off your face, then a big, floppy hat will be suitable. A floppy hat will suit you in this situation: it's appropriate for the pool, and helpful for you.
But the same big, floppy hat is unsuitable for school. It'll get in your way, and it'll annoy you and your classmates.
As you can see, suitable things depend on the situation. Pepperoni pizza might be a perfectly suitable meal for you, but it could be unsuitable for your one friend who can't eat gluten and your other friend who doesn't eat meat.

You can use either of the two ideas I'll suggest, or you can invent your own. Include as much detail as you can!
(Source) Write a sentence with the word SUIT or SUITABLE:
Remember: suitable things are good because they work well for the specific person or the specific situation. And suits are full sets of clothing that fit people just right, or full sets of anything that give you exactly what you need.
Idea 1: "(Something) is a suitable activity for outdoors, but not indoors, because (of some reason)."
Idea 2: "Not everyone enjoys (some specific kind of food or activity), but it suits me very well."
