Kiki Riki- extremely tight…not so tzniyus.
Modasty-pretty good, but fades and gets ruined after a while. I hear the newer ones are better though
Basic you- Not worth every day shells, if you need a specific color for one shirt they are super cheap. But extremely junky. I’ve seen worse though.
Most chains stores also have in the back. Those are really good quality but expensive and you need to carefully see if they are tzniyus. But then again, just cuz its a frum store doesn’t mean its tzniyus either 🙂
Stardust is a company sold in many shuk type stores. Shells are between 30-60 depeding on the store and from my expirience they are even MORE comfortable than Modasty and last longer.
