learn_russian | Shopping in Russia

Hello all,
I work in American retail and interact with Russian tourists every so often. Wanting to practice whenever possible, I would like to know the names of various garments as well as other general phrases used while helping customers in a clothing store.

Please translate the following into proper Russian:

fashion
clothing
Do you need assistance?
fitting room
May I start you a fitting room (while you continue shopping)?
size
extra small / small / medium / large / extra large
What size do you need?
We have none of that size left.
We don't carry that size.
We carry even number sizes only.
Let me check in the back (stockroom).
We have mirrors in the back of the store and by the entrance.
Your total comes to...

bathing suit
dress / gown
jumper / romper
negligee (bra, corset, panties)

If there was a specific item of clothing I forgot to mention, please let me know. Finally, I'm very curious about the overall shopping experience in Russia. Are there any different courtesies one shows while shopping in Russia vs. America? What are the most popular styles, brands, and fashion publications/influences? What garments are necessary for daily life in Moscow and St Petersburg? Has the luxury clothing market been successful in post-Soviet Russia? Comparisons between the fashion economies of America and Russia would be greatly appreciated if known.

Thank you for your time, I am excited to learn all this information!
