This pro life tip brought to you by The Irritation of Removing Uncomfortable Tags.
Use a seamripper to remove the stitches that attach a tag and the garment itself. See attached picture for a demonstration of this. Seamrippers are cheap (~1 USD is typical) and available at any store with even a token sewing section, such as walmart or target, and some grocery stores as well. Using a seamripper lets you remove the tag entirely, while cutting the tag off usually leaves behind a sliver of the tag fabric that can be uncomfortable.
Depending on the fabric, placement of the seam, discomfort caused by the tag, and whether you have access to a sewing machine, whether or not it’s worth undoing the overlock seam to remove a tag and then mending the new hole varies. Personally I’ve left these and removed them on different garments.
