I'm planning to put a lace curtain & a blackout curtain over above the window. Do you think I need another curtain over at sliding door?

Note that, there is toilet section before the built-in cabinet. So, I may need a silk curtain at sliding door, but uncertain if lace curtain is needed too. Feels like there's plenty of curtains and laces hahah.

Reason I need a silk curtain at sliding door is because the weather's hot here. After switching off AC, I think at least with the silk curtain, it will keep the room cooler slightly longer?? And also, I'm lazy to walk all the way up to the window to close curtains before showering. Give me your opinions, in terms of convenience & aesthetic.
