The reasons you’re supposed to wait is because the wires can damage your incision and cause infection (even if you think you are healed) and the wires can push the implants up to much and leave them to style to high. Plus they can really hurt your boobs
It’s advised for a reason. If you can’t hack your sports bras, get a lovely non-wired one, m&s do an illusions range, which is comfy and gives a great shape xx
