Over 30 denim lines in this North End boutique

Noteworthy for: Shoppers repeatedly extol the friendly and expert staff who will direct you not to the latest cut or most expensive label but to the pair that best fits your body and style.

Word to the wise: In-jean-ius also stocks tops, shoes, and accessories, including HOBO bags and Michael Stars T-shirts.

For many women, once they've found a denim brand and fit that works for their figure, they'll never stray. Unfortunately, this kind of commitment traps them in trends that were stylish in college but become increasingly embarrassing as the years wear on. Staying ahead of the curve – or even just keeping up – is tricky when not everyone can rock skinny-legs or high waists.

In-jean-ius, fortunately, is polyamorous and even wanton with its partners, stocking over 30 brands of high-end designer jeans and lesser-known labels, including Citizens of Humanity, Rock and Republic, Denim for Immortality, Hudson, Joe's, Michael Stars, Taverniti, Antik, and Kasil.
