my sister gave me this plaid skirt, but i'm not sure how to make it look cute, but 90's style. any ideas?

i was thinking about a tank top under a white dress shirt with a couple buttons on the top undone, but i thought that would be a little slutty...

I think anything White or DARK Navy blue would look good with it.

Be careful and don't make the shirts too tight though because you might look like a slutty school girl

I think this though mainly depends on what color the plaid is.

I don't believe you stated... If you could find a picture of it, it would help greatly or atleast explain it

I'd wear dark tights under them (not leggings) and maybe a lightweight knit sweater on top, like this:

Its khaki with maroon, gold, green, and orange stripes.

yeah that pic ^^ was a good example. you want to kinda play up the school girl look, just don't actually look like you're a school girl, you know? look at the plaid at what colors are in the plaid and then play up on those. is it a blue/red/white plaid? play up on the red with like a red henley top or a blue v-neck. make it cute and a bit sexy (not slutty school girl!!) a perfect way to play it up for fall is to pair it with some tights and ankle boots...ooooh and with a matching cardigan! here's my perfect outfit with that theme:
-plaid skirt (lets say its the red/navy/white scheme)
-white, black, or navy tank/top
-navy, charcol, or black cardigan (make it a big one to balance the shortness of the skirt)
-grey tights
-black ankle boots.
perfect!!
