You have to remember when wearing a high waisted skirt the shirt has to be tucked in and pretty plain. As in solid colored. If you wear a high waisted skirt with a floral/striped/polka-dotted shirt that would take attention away from your skirt. When wearing a high waisted skirt that should be the main attraction of your outfit. As in what people look at most. With all those skirt you bought I would suggest a Plain White V-Neck Shirt. Or maybe a white ribbed tank and a heather grey cardigan. As for shoes with the first two I would say either silver sandals or plain all black Converse low tops. For the last yellow one I would suggest either all black,all white,or yellow Converse. If not Converse I would suggest white sandals with the ribbed tank. Also just to add long necklaces and thick belts look GREAT with high waisted skirts. It gives you a very awsome looking Vintage look.
Sorry this is so long but it gives you a lot of information.
Okay well hope this helps!
oh and P.S:If you dont have Converse and sandals you could pair them with Gladiators or Heels . The gladiators/heels being black,gold,silver, or white.
L.o.l i'm pretty fashion forward,not to be conceited. Plus I absolutely love high waisted skirts and get complemented a lot when wearing them.
