380cc Motiva Implants for 5f4 / 120lbs

I'm standing at 5f4 (163cm), weighing 120lbs (55kg) asian. I had my first implant done 11 years ago (200-250cc, about 10cm) and I'm scheduled to remove and doctor has advised to put in 380cc (demi profile) motiva ergonomic joy implants. I'm afraid it might look too huge, anyone has similar built and what's your implant size done? Care to share your experience? Thanks in advance.
