Im 5'8" and 160lbs and currently a b cup. Is 525cc implants to big or will it give me a nice d cup?

A plastic surgeon will make measurements and then give you guidance on the devices.Please find an experienced Board Certified Plastic Surgeon and member of the Aesthetic Society using the Smart Beauty Guide. These Plastic Surgeons can guide you on all aspects of facial surgery, breast augmentation and body procedures including tummy tucks or mommy makeovers!

Your height, weight, and starting cup size are helpful, but not enough information to decide what type of augmentation to expect with a 525 cc implant.  Volume (525 cc) is less valuable data than dimensions (width and projection) in my opinion.  525 cc could be a very wide flat implant for a broad chested woman who wants small augmentation.  525  cc could also be narrow implant with "ultra-high" or "full" profile that would add two or more cup sizes for thin woman with narrow shoulders and chest.  Find a good plastic surgeon, listen to recommendations and reasons for recommendations, try sizes and styles on in office (and/or computer simulation), then make your best decision.  Size is only one component of many that contribute to a quality result.  Others are shape, symmetry, texture, scars, preservation of sensation, avoiding implant visibility, and more.

Thank you for your question.  I agree with other surgeons that you need a consultation and examination by a board certified plastic surgeon.  You will have the opportunity to try different breast implant sizers to evaluate how various size options will look on you.  Cup size is impossible to comment on because different retailers cell the same cup size under different labels.  That is to say AC cup bra and one retailer can be called a D cup bra at a different retailer.  Please consult a plastic surgeon, have examination and have a sizing session to provide a weight what size looks good on you.  Generally speaking 525 cc is a very large implant in my opinion.
