I understand you can't wear wired bras and have been recommended to purchase a sport bra but any tips of the type? Should I get a maximum impact one or just a soft one? Should it have shape or completely plane? Zip at the front or back clips? Also should I buy it in my new planned size or slightly larger? I am currently 34H going to 34D post surgery. Any other tips? My friend recommend zip up or button up tops for the first few weeks.
