I love that my Flow Y bras are completely covered when I wear Swiftly Tech tank tops (as seen in the picture) but hate how much the straps dig into my traps. I wanted to try out the Wunder Train Strappy bras instead but don’t have a store near me. Does anyone have a reference of how much the straps would show under Swiftly Tech tanks as it seems like the position of the straps wouldn’t allow for a complete conceal. Also, is there a huge difference between A/B version vs C/D version? Thank you!!
