There are ways that you can dress to look a bit smaller........but I think she looks great here.
BTW.....I don't think any of the girls/women look too skinny.....you say that as if they look emaciated like Nicole Richie and Lindsay Lohan.........now that's something to be worried about. If the girls can continue to perform at the intensity that they do, then they are healthy.Besides, after a certain age, baby fat just becomes fat.
^I know a lot of fans are probably sad that she's leaving, but that's rather shortsighted. H!P did help her establish and idol career and probably gave her the opportunity to create a lot of precious memories. So even though they are disbanding Biyuuden and graduating her, she has a lot to be thankful for because of them.
