thermal underwear

where would I get this girls? Have a cold and feeling really shivery. Everyone at work is passing out with the heat except me What exactly is thermal under?

Hiya, Feeling your pain.The same week i found i was pregnant i got a brutal cold.3 weeks on still stuffed up.Read somewhere that the immune system is lowered so as not to reject bubs. Thermal under wear is just thick cotton vests.Kinda what your granny would wear. But in my opinion if it keeps you warm thats all that counts. You can get it any where in Pennys or Dunnes in the undies section.
