Slicks is a neat little store in Boothbay harbor that sells women's clothing. Much of the clothing is of natural fabrics like cotton, linen, and wool. They have a wide selection of items to choose from, both casual wear and dressier things.
The clothes tend to be a little on the pricey side, but you really are paying for quality. I have a tank top that my sister bought and passed on, that has been owned by myself or my sister for 10 years. It's pretty basic and classic, not trendy, and it has held up well.
They occasionally have really good sales, and that is the time to go! Their end of the season sale is especially great.
