Kiton tie untipped interlining visible???

totally normal

Yes this is normal and also how my un-tipped 7 folds are made.

the right thing to do in the case of that fabric is to die the interlining, I've done that for the reason you mention but you are not going to find that in RTW ties. If the tie is made in an open/porous fabric and you add a white interlining to it, the fabric will look lighter where the interlining is. Take that as part of the tie's appeal at this point. Although the lighting in your last pic is bad and you could also just have a tie with a defect in the fabric.

Example of dyed lining:

 

Did you look in the skinny end of the tie all the way up? I've bought plenty of tie without this, I don't think it is anything to be worried about (unless you're planning on selling it on and then would like to know if it's cashmere or wool )

 

 

Was just look for this picture.. Thanks for posting. This is also an example of (perhaps) how the lining should be in a untipped tie.. . This would prevent it looking funny as in the OP's 3rd picture..

It's easy to have it dyed.
