How to get a more feminine shape?

Your shape IS your shape. You cannot change the width of your hips or shoulders, your height (without shoes), how your muscles are attached, etc.
You can "enhance" your look with lifting and body fat loss.

This. You're going to get a lot further along in life by learning to love the body you have,than by trying to change it to something to you can't. Heavy lifting can give you some change along with body fat reduction, the muscle definition will increase if you do that, and your waist will show a little more. As you get older your body will naturally sharpen some; in the young there is natural rounding to the face and body. I'd stay away from things like Spanx and butt shapers, and just learn some fashions tips that enhance your natural shape. You'd be amazed how learning to dress can make a huge difference in your look.

I assume you mean- how do you get your banana/ruler shape to turn into an hourglass?
Answer- you can't without surgery.
I have the ruler shape/boyish/banana/straightish.
1. Become content with your shape.
2. improve what you can. (Bigger butt muscle, maybe work on shoulders)
3. don't get caught up in what makes a female shape...female.

What banana shape? She has a defined waist.

I agree with the other posters - you look feminine!

But I think I also understand what you're saying. You do have something of the "rectangle" shape (probably the most common female shape) - hips and bust almost the same, and waist is smaller, but not enough to qualify as "hourglass." The standards are silly, but in society we've come to see hourglass as the most feminine.

As Ninerbuff said, your shape is your shape. You can't do much to change it, aside from surgery. But there are some things to give the look of a more hourglass figure, if that's what you want. Lift heavy weights. Yep, lifting will give you a feminine look. It'll help reduce body fat % so the waist may slim down. You may also get a bit broader look in the shoulders (assuming you have a build for it, there, but a bit of muscle added in the chest and shoulders can help) and a nice, round booty from squats and deadlifts and such. For me, at least, it gives a bit more of the illusion of a narrower waist, although again it depends on your build. (Look into a compound lifting program if you're interested).

Do you have a vagina, female reproductive organs (I can see you have breasts) and do you identify as female?

Congratulations, you already have a feminine shape and the shape you have is determined by genetics. You can tweek it with specialized exercise routines (recomposition) but, overall, what you have is what you have without getting into surgical alterations.

Damnit Brower. You beat me to it.

Tis my goal to make your points for you before you get the chance. Mwahahahahahaha!

I was expecting something masculine-facial hair, large shoulders, narrow waist, narrow hips, muscles, hairy chest & extremities.

You have a serious body image problem.

To this I would simply say "Keep doing what you're doing.....*drooool*"

Edit: I didn't realize how ripped this man was.. damn.

OP, you look perfect to me. You have a very healthy looking body, with what appears to be a body fat amount in the normal range. Heck, you even appear to have the much-strived-for, but rarely achieved "thigh gap" going on in your photo! I imagine many are jealous of that.

However, you are looking to improve your shape for some reason, and asking for advice about that. What you can do is start lifting weighs to help tone your muscles, which will help give definition and might tuck in your waist line a bit more, if that is what you seek. I don't know if it would be advisable for you to lose any weight, and you should refer to your doctor for that information, but certainly if you are healthy enough for exercise, you might feel better about your appearance in 2 months if you follow a good weight lifting or muscle toning program. Check with your gym to see about a session with a personal trainer to get on the right track. Best of luck!
