For the top, I chose a medium size, which is the size I typically wear for built-in tops or sports bras. I usually wear a size small in tops. Regarding the shorts, I opted for a size small for my 26/37 measurements. Since I don’t have a significant waist, I would need a medium size to flip the waist without creating a muffin top effect in that area. LTKootd LTKgrwm LTKPetite
