Liang Rou Women s Crewneck Stretch Top Bottom Thin Thermal Underwear Set 1 Set Apricot XS-S (0 2 4 6)

Q: What size you recommend for someone who wear size 5, 7 and 9 in pants?

I ware a size 7. What size should I order

Q: Are these thin enough to wear under tight jeans without making one look heavier?

The material is very thin and silky. I wore them under my jeans but they were not really tight jeans. I believe they will work under tight jeans unless they are extremely tight and fit more like leggings.

Q: Is the pant measure by the inseam or the length from the side?

Usually the description will indicate the inseam, for example, petite inseam 28”; regular inseam 30”; tall inseam 32”. I don’t recall seeing a description showing a measurement for the outside length of pants legs.
