Red circles from breast forms

[Jhow]

Just got my first breast forms and love them however had a problem when removed there were red circles around the area where the forms were attached  have watched Janet's video several times and followed directions but put my bra on just after attaching forms. Could the bra have been too tight?  Left forms and bra on all day. With forms in place measured band and breast, used online calculator to determine bra size did hav the proper size but bra was tight. Any ideas would be appreciated. Am not allergic to latex
Love
