The answer- Skirt Shirts (or shirts-turned-onesies). They kind of remind me of the bodysuits I liked to wear in 7th grade. Except looser, with less crazy floral prints. And way cuter.
To make one of these gems to pair with a high-waisted skirt near you-
Find a onesie that you’re ok with cutting up (I have a whole pile that are stained for just such purposes). Lay the shirt you’re converting on top of the onesie to measure how much ‘bottom half’ you’ll need. Mark with a fabric pen.
One unrelated, unfortunate confession- I think I had a bodysuit-turtleneck in junior high (that I wore with my favorite Guess jeans with a ‘Guess’ triangle on the back pocket). Oh boy. Tell me that some of you forayed into the ‘bodysuit’ world as well? And while you’re at it, any reassurances that those will never come back in style?
