i couldnt wear mine for the first week or so but after that, i loved it and wouldnt take it off! i thought it was hurting them so tried like 4 other bras but they was all the same or worse so i stuck with the macom.. it defo doesnt flatten them it helps hold them in place well, and even with overs they will get bigger over time so jus wait til they drop & they look so much fuller!! xx
