アナスタシア スウェットパンツ

I've washed these three times already and the cotton hasn't pilled or shrunk a bit. The side pockets actually fit my phone, and the drawstring on the inside waistband stays put instead of digging in.

The cotton is thick enough that these don't feel like cheap pajama pants, and the side pockets actually hold my phone without sagging. The 28-inch inseam hits right at my ankle, which is perfect since I'm 5'6".

These have become my go-to for lounging around the house, and the side pockets are actually deep enough to hold my phone without it falling out. Only gripe is the 28" inseam runs a bit short on me, so they hit above the ankle.
