(If this shows up ginormous, forgive me!!)
Have options that you can wear whether the shirt is big on you (you might not have much of a choice in sizes) or if it's more fitted on you. Think neutral colors - beige/khaki, denim, white, even brown.
Some ideas of dressing them up:
- If the t-shirt is longer on you, put a neutral belt over the shirt. You can wear it at your natural waist or your hips, depending on what looks best on you.
- If it's able to be tucked in, wear a silver or gold-toned belt and shoes with similar tones, or tie a cute ribbon/bow or scarf in your belt loops.
- Make sure that skirts aren't so short that if you bend over, you can see your cheeks. You may catch a breeze, so keep an eye on flouncy skirts.
- Make sure that shorts aren't super tight (no camel toe).
- Make sure that items made with lighter fabrics and colors are lined.
- Wear nude-colored underwear.
- Watch for VPL (visible panty lines).
Some bottoms to consider:
--------------
A pencil-type denim skirt (can be dressed up or down, definitely a wardrobe staple!)

A flouncy white skirt (not too short!) - here's one from Banana Republic but they have them everywhere. MAKE SURE it's not see-through (this one is lined)!
