Tailor
person who makes, repairs, or alters clothing professionally, typically men's clothing
Would an expensive tailor use adhesive to create a shorter hem on slacks?
Adhesive hems are usually performed at home with a DIY kit. Professionally hemmed pants are created using a needle and thread.
Is a tailor professional when creating hems? Is using adhesive a professional way to create hems? Are #1 and #2 the same?
