That's irrelevant guys but What would be the best clothes for first date ? I don't want to...

just wear something casual

You don't need to show too much skin to look sexy. Wear something that is either form-fitting and/or enhances the best parts of your body. But if you feel like showing more of your skin then go for it.

The best thing to wear is something that makes you feel self-confident. It shows.

I think wearing a very basic outfit like a simple t-shirt and jeans/skirt works. Then use unique accessories and place care in the details (hair, makeup, skin, etc). You don't look like you are overly trying but still can show your own style and look cute.

Agree

For Cute and Sexy you should wear fitted clothing, like a fitted skirt and shirt that has a cute design and cute accessories so you can show off your curves too? Personally that’s what I would do ^^

This is just something I'd do so you may or may not take the advice: For a first date, I'd wear a dress and do my hair generally for a first great impression. For the rest of the dates (excluding special dates) I would just look casual like a denim jacket over a yellow t-shirt and blue jeans with sneakers.

What I would generally suggest is for you to wear something that makes you feel beautiful and something that is comfortable to wear for a whole day.
