I have promoted to Size 'L'......

This afternoon went for a spending spree with Liwen. Tried alot of clothes and nothing caught my eyes... I looked so FAT in all the clothes...I am no longer wearing size M, have promoted to L ..Ohmigod!!!!!!!that's really bad!!! really BAD.I need to wear something to conceal all my fatty area. How am I going keep myself slim and wearing all those pretty and sexy clothes but yet can still enjoy all the irresistible mouth-watering food? *headache*
