When dealing with previously owned clothing the size listed on the tag may or may not be accurate.
Clothing may shrink and/or stretch over the years not to mention the variations in fit from brand to brand.
We measure each item using the chart listed here as a guide.
Laying the item on a flat surface, we measure across from armpit to armpit,
this is the “pit to pit” measurements listed in each item description.
Then we measure from collar to bottom hem to determine length of item,
this is the “collar to hem” measurement listed in every description.
Take one of your favorite shirts and measure it as mentioned above, then compare your measurements with measurements listed here to get an idea of how item will fit you.
This will be much more accurate than just going by the tag size on shirt, in some cases the tag has been removed or has faded so this will be the only way to know if item will fit properly.
