What Happens During an Implant Sizer Fitting?

Trial sizers worn inside a bra let you see and feel candidate volumes in the mirror — a low-tech step that often settles the size question faster than numbers do.

A sizer fitting places sample implants of different volumes into an unpadded bra so you can look at each option in the mirror, in your own clothes, from several angles. Many consultations pair the fitting with measurements of chest width and tissue thickness that narrow the realistic range first.

Why clinics still use a bra and a mirror

External sizers cannot copy how an implant sits under tissue, but they communicate proportion — how a volume reads against your shoulders, waist, and wardrobe. Bringing a fitted shirt you wear often makes the comparison more honest than a loose gown.

The volume that looks right differs with frame, tissue elasticity, and personal taste, so two people can leave the same fitting with different answers. Use the session to shortlist two or three sizes, then let the specialist reconcile the shortlist with what your measurements support.
