Bastien Boots

I've never worn these boots so can't speak from personal experience, but the company description looks perfect for missionary use:

Bastien winter boots are headquartered in Quebec, Canada and have been proudly manufacturing winter boots to meticulous standards since 1932. The Bastien brand represents stylish, warm, waterproof boots. They are fortunate to have a team of five award winning footwear designers. The Bastien promise is to produce quality, casually styled, comfortable, fashionable winter boots. Winter is real. Demand the brand!

Here are some good options:



Also, here are some Blondo boots that look promising. Also waterproofed and insulated.

LDS Sister Missionary Coats

Here are some coats that meet the sister missionary guidelines.

Ecco

Clarks

Clarks is the brand I most often hear recommended for sister missionaries.  Their collection of comfort shoes carry some very cute looks for sister missionaries.  The prices are relatively affordable, too.  These links take you to Endless, an online shoe store that offers free shipping both ways.  So, if the shoes don't work, you can return them for free.
Here are some of my recommendations:

Danskos

Recently I did a survey of my return missionary friends as to which shoes they preferred.  Clarks won out on reviews for their great price, durability, and comfort- but another brand that came up again and again was Dansko.  Dansko's are known for having excellent arch support and for being extremely long-lasting.

Here are the styles in the current Dansko line that are mission-appropriate:

Grand Opening!

The website is finally up and running.  We are starting out with some of the simple basics- long skirts, blouses, blazers, etc.  Hopefully, pending success of the website, we will be able to offer a wider range of clothing and accessories.  Check it out:
