Hello, 
Thanks for sharing your photos. The good news is that you can definitely achieve the look you want with an implant alone. I have some patients with an almost identical shape to you so if you'd like to email me at dralex@parkclinicsydney I can share some before and after photos with you (Can't really do this on the forum unfortunately). A consultation with a Vectra machine will also be useful for planning which we also use in our practice.
Kindest regards,
Alex

Thanks for getting in touch.You do have some asymmetry with the left being slightly larger than the right.None the less a simple breast augmentation without a lift will be enough to achieve your goals.You may require asymmetric implants to achieve this.Tear drop implants most likely in a high profile style.
I hope this helps and good luck.

Hi there,
Thank you for your question and photos.
I think you'll have a great natural full looking result with breast augmentation alone without lift.
I would personally recommend a dual plane approach with a high profile anatomical shaped implant to both fill and lift the deflated breast skin envelope while maintaining a natural full looking result.
Obviously it'll be best to seek an in person consultation with a specialist plastic surgeon for further clinical assessment. Feel free to submit an enquiry to my practice via PSF if I can be of any further assistance.
Hope that helps.
Best wishes
