It must be the oxygenated air
Some days are just for comfortable clothes. For simple combinations, not much to worry about so you can concentrate on whatver is important.
In situations like this I always wear leggings. Recently with this top, it covers the parts I dont want show in leggings like my butt or crotch but takes to focus to my hips so you can still see how flattering they look on my body.
This is a great example how clothes can change how your body looks. My legs look like they were a normal height, keep that in mind when you see the friday look because they look wasy longer than here. In reality? Something in between.
