I personally would appreciate some restraint, but like everything else there is a place for it. I'm not happy to see thin people showing their rears and breasts off in the supermarket, either. But I won't hold it against anyone if they want to wear a bikini at the pool, no matter how big they are. I don't begrudge a large woman the ability to wear a skimpy shirt on a hot day at the zoo, either. I just appreciate a little situational decorum. When not pregnant I'm pretty decent looking body-wise, and I don't wear skimpy things out-and-about either.
But look at the language - I'd *appreciate* a little restraint in the what-to-wear-when department, but I really think that this is something that isn't that important - what do I care if they're showing fat, how does that really affect me? Why do I even think it's gross? One of the sexiest ladies I know has some extra fat on her (she isn't huge, but is at least 25 lbs overweight), and she puts on a bikini and looks stunning - it is all about her confidence and how she carries herself. But she doesn't go to class with 10 inches of belly showing.
And in all fairness, it is difficult to get plus-sized clothing that fits well and is at all stylish. I've shopped with an aunt and cousin that are quite well overweight (in the 300-325 lb range at 5'2") and it is TOUGH to find good clothes. Ever worn the wrong thing out of despiration? I'm sure it happens a lot more when it is so difficult to find the "right" thing and everyone is hyper-critical of you (and has their own opinion about what it is "right" for you to wear).
