I would disagree with your first doctor. If the breast pocket is made properly, there is no need to wear a bra 24/7 after 1-2 weeks. The capsule of scar tissue should be well formed by then, holding the implant in place. You should be able to submerge in water when the wounds are completely healed (usually by 2-3 weeks). However, swimming and other upper body exercise should be delayed for at least 4-6 weeks, to prevent bleeding or displacement of the implants. Different surgeons will vary on their choice of bras. The main thing is that you should not wear an underwire for at least 1 month, and you should have good support without flattening of the implants. The implants may, initially, look high, and then descend into their normal position over the following few months. If one, or both, implants are not descending quickly enough, you may need a chest band, instead of a bra, to speed the process before the capsules are well formed. You do,however, need to be careful not to use too much pressure. ( If an implant descends too far, you may need surgical correction.) Good luck.
