Shirt Too Short, Sheer or Low Cut? Pants Too Low?
Find some long tank tops or buy some cheap ones, and make sure they go down to your hips at least so they won't be too short after you wash them. Get several colors, like black and plain white (no logo) and maybe multi-colored rainbow stripes so they can match anything. Wear them under your t-shirts and tops. It's hard to find jeans that aren't too low and shirts that aren't too short, so this is a good quick fix until you can find some better clothes. The tank top is to keep your stomach covered but it also covers your chest if the shirt is too low cut. The tank top under the shirt doesn't make you too hot in the summer because it's thin with no sleeves. And it looks cute, things always look cuter with layers.
It's easier to find cute baggy overalls than it is to find jeans that aren't low. So think about looking for overalls or a jumpsuit of some type. Here's a picture of me in my overalls so you can see what I mean: I'm not talking about ugly overalls, I'm talkin' about cute overalls with lots of pockets and other stuff. They're good because no matter what shirt you wear under 'em you don't have to worry about your stomach showing when you bend and move. Wear your tighter shirts under baggy overalls. One of the "fashion laws" is that you should wear one loose-fitting thing and one snugger-fitting thing together. For example: with loose or baggy pants you wear a snugger top. With snug pants you should wear a looser shirt. Same thing applies with skirts and shorts. If you wear both tight or both baggy it tends to make you look fat. So with baggy overalls don't wear a baggy t-shirt too. Skirt Too Short? Pants Too Low or Tight?
If you have a skirt that's become too short you can still wear it as a fashion accessory. Wear it with pants underneath it or wear it over a longer skirt. It's like having a new outfit. If you have pants that are too low or look too tight you can wear the short skirt over them. The skirt can help cover your middle as well as your back side. Like I said before, layers make modesty look cute.
