The stitches are unwinding
This is another easy way to know that your panty is in an embarrassing s state. Some low-quality panties won't have stitches that are properly secured but in this case, we are talking about the ones that have just been worn too many times.
This type of underwear can humiliate you because imagine walking unknowingly with a long thread hanging from your trouser or skirt. At this point, your panty is literally falling apart and you need a replacement ASAP.
It's fadedThere is nothing sexy about a faded brief. Yes, you loved the rich colour it had at the beginning but right now that's all washed away.
If you want to preserve the colour longer, next time, don't wash them in hot water. This can cause the colours to bleed more quickly so try and stick to warm water.
It has holes in itThis one is a direct indication that your underwear has expired. The holes should already tell you that your undies have worked tirelessly for so long and now they need their retirement package right away.
Don't be caught slipping with torn underwear or even one that you tried to stitch up discreetly. Start making plans for a new one because that one is now too old.
