Everlane, known for quality-made basics at a good price, is having a home try on promotion. You can order up to 10 items (think you must order at least 5) and they ship free and returns are free. You will need to enter credit card info, but they only charge for what you keep..no looking for credits on you card statement. The offerings are preselected from their best selling products..mostly tees, silk tanks and blouses, and cashmere sweaters. I ordered 10 items, duplicates in different sizes of several. Figured this would be a good time to figure out fit.

ETA: Just found out in my confirmation email that this promotion is for first time customers only. Guess it's directed at people like me who always wanted to order but never pulled the trigger.
