sis m_lim i was in a a/c room nearly 24/7 for my ge-lai so it wasn't hot. It was only when I had my meals outside when I would sweat and I'd punas and change after every meal. I bought girdles from landmark lang, like 300 bucks each. I also bought tihs brand of high waist semi girdle panty which I loved! I bought a large and medium size, wore the large mga first 2 weeks then medium na afterwards.
