I've never liked underwired bra's for 2 reasons:
First the wire starts poking through on one side and annoying the hell out of me when I keep having to push it back in every 5 minutes so I pull the wire out of that side and can never get the second wire out.
That causes the second reason. It feels like the one remaining wire is trying to bury through my chest and into my ribs.
I prefer non-wired bra's because of those 2 reason's but I'm a totally natural GG cup and they don't seem to make them non-wired in that size! Finding one is like finding a pin head buried in the Sahara desert!
