This has been my "mom-uniform" of late:
top left: TNA sweater
top right: my old worn-in gap jeans
bottom left: striped shirt (gap)
bottom right: a pair of rubber boots (mine were purchased a few years back at good-ole walmart for about $10)
underneath I usually am wearing a nursing tank... we're not going for super-sexy here folks, just comfort!
Do you have a "mom-uniform"?
