Underwear is irritating me beyond belief!!

I swear I think it is time to go commando lol. I have gotten bigger around the hips, stomach and boobs even though I haven't gained a pound so my clothes don't fit anymore. Most of all my underwear is bugging me as it keeps digging in at the top of my thighs. I have been wearing boxers the past few days to try and stop this but I have actually gotten changed 6 times today because of my pants irritating me lol. I'm either going to go commando any time I can or I'll have to buy lots of new underwear already. Anyone else having this problem?
