Agree with
@Swanky . Having face-framing bangs or bangs that cover the forehead to a certain extent require commitment.
I've never had curtain bangs but I did have the classic forehead bang, that were a little more side swept and they were kind of a pain to manage.
There are days no matter how hard you try to style, the hair won't listen to you. There's only so much heat and product you can use on it before it either gets damaged, oily, sticky or hard.
Depending on skin type, bangs also can make the forehead oily and prone to acne. If you wear foundation on your face, then you have a higher chance of getting foundation on your hair.
Also forget about wearing a hat, in general they mess up bangs or bend them in a funny direction. If they get temporarily clipped out of the way, then the clip or pin can bend it funny too after you take them off.
In addition, depending on how much bang you want, they can also obscure your vision. If you've had bangs before, you're probably used to to it (I am). If not, you'll definitely find it a pain.
It's easier to see the proportions of the face when you can see where the eyes, eyebrows, nose and mouth are.
Tbh for you it's hard to say. I'd advise against curtain bangs depending on how heavy they are. If they cover up a lot of your forehead, they may make the lower half of your face appear larger.
Here's a quick google search on curtain bangs. You can see some frame the face more than others. Some are more heavy, some are more wispy, some cover up the forehead more, some are longer, some are shorter.
I guess the good thing about curtain bangs is that if you have the long curtain bangs and don't like them, you can always push it out of the way and let it grow out.
If they're short curtain bangs, you'll have to wait a bit for them to grow out.
I believe you can always use a photo filter or photo app to see what you'd look like with curtain bangs and see if you like them.
