These Spanx twill pants are amazing. Thick enough to not show anything underneath, yet breathable enough for summer. I'm 5'5" and am wearing the Regular length. I could wear them with a medium or low heel, but doesn't look great with a flat. I'm typically a 4 and I chose the Small. There's a little room in them, but I couldn't have gone to the XS. Styled them with an EVEREVE linen blazer, some acrylic bracelets, Amazon wedge heels and a Freja bag! LTKSummerEdit LTKOver40 LTKStyleTip
