Help with words for use in talking to a seamstress.

I have a seamstress from Russia in a shop I deliver to and I am regularly explaining things to her on invoices so she knows what is expected. She understands some English but can't really read it at all. On the other hand, I can read Cyrillic almost as fast as English and my Russian pronunciation is pretty good, but I don't know many words. For whatever reason years ago I decided to learn to write it before speaking it and then didn't follow up.

Anyways, I'm hoping that someone can provide some words or phrases in context for some of the following situations. Thank you in advance. It would make it easier for me to compare American words on her paper with Russian words she might be familiar with. I'm not fully trusting of Google translate for context and proper respect; this lady is far more experienced than I and while she enjoys my attempts I still don't want to use an improper or disrespectful voice.

• Left side and right side, I already know Nalyeva/Naprava but is this sufficient when referring to the side of a garment? Like take-in the left side...
• Hem, as in take up the length.
• Repair by sewing, is it enough to say "repair" ?
• Reinforce loose buttons, or replace missing or broken buttons.
• Replace zipper - she has this one down but I am just interested.
• tighten up as in the chest area of a suit jacket
• needs pressing afterwards
• needs cleaning afterwards

I have subscribed to duolingo but something I think that site lacks is context. Most people are learning a language for a reason, not just for the heck of it. I know the site has to approach it properly from early stages but I find it less practical than it should be. It feels really condescending for me to use elementary "my name is, good afternoon" phrases when talking to a native of any language in the workforce. After all, I have never heard a true Spanish-speaker use "Hola" at any time. It is more seeming to know some industry words to get your point across.

Thanks again.
