Eh. Vanity sizing and lack of standards across brands can make anyone bananas.
Try to just think about the fit on
your body and ignore the label number. There's no fashion police checking tags. And I'd much rather see people in figure flattering clothes that not. Too tight/too baggy doesn't help anyone.
This may sound blunt, and I admit when I'm putzing around the house I don't care what I have on. But I have some friends that I wish would just listen to me and go up or down a size when dressing to go out.
The overweight chickie? Go down, dude. Hiding in baggy clothes does nothing for you. So you are fat. So am I! But it isn't like loose baggy clothes is hiding the fatness. We know you are still overweight. So go for well dressed overweight rather than ill fitting!
The regular size chickie? Go up dude. Squeezing yourself into the next size down just because you can squeeze doesn't look attractive. You look like sausage sticking out in lumpy bits. Go up a size so it fits your form nicely. We know you are regular size. You will still look regular size even if you size up. Go for well dressed regular rather than ill fitting!
HTH!
