Wow - lots of questions! Stitch Fix is a service that sends you a box of five clothing items. It's not a subscription service - you pay for the items you like and send the others back. If you keep the whole box, you get a discount though. I filled out the style profile and they will also review your Pinterest board, if you have one (I don't ), to get a better idea of your style. You can also write a note to your stylist if you have specific needs. For example, I met a women who had just bought a pair of silver oxfords and she asked for stuff to go with her new shoes. It's fun to get a surprise box of clothes in the mail.
I've had good luck with them nailing my style, but I had to ask for a different stylist after the first 2 or 3 boxes. She just played it too safe - it was all stuff I already had - skinny jeans, cardigans, black pants, a plaid scarf. Stuff like that - my style but also very safe. My sister also does it and she always gets super cute stuff - shoes, dresses, skirts, jewelry, etc. So I asked for a different stylist, told them to stop sending me denim, and I've loved the last couple boxes. I've had good luck with items fitting me but they'll exchange sizes for free.
I'm not sure why Domino isn't in any of these pictures. I'm sure she's close by.
Deborah - I did Birchbox for a few months. Also a birthday gift from my sister. It was fun but I started to get overwhelmed with samples eventually. It's been a year since I quit and I'm still going through sample bottles. I found some great products through them.
