kindly look at my profile pictures for comparison. anyway I want to lose weight Because there's a korean fever here in my country and I so envy korean faces and their cute little bodies. I just bought a korean jumpsuit short refer to my profile pics but it doesn't fit me well Because its supposed to be loose but since I'm kinda thick it ends up hugging my bod. I'm thinking to lose 8 kilos to look like that of a korean body but my sister disagree Because she thinks I should lose around 10-15 kilos. what do you think? thanks!
