There are several boutiques now operating in the fashion industry. Each one has to stand out on its own in order to get recognized. That's why they need a simple, recognizable, and unique logo.
A high-end boutique would be well represented by gold and black/white contrasts in their logo. A more casual venture might want bright colors like pink and purple for appealing to a feminine audience.
The symbols for a boutique logo would depend on your target audience. If you're catering to mostly women, a glamorous feminine profile would be relevant. Many boutiques also simply use a hanger image with their name written below or incorporated into it. This is an eye-catching idea that could make a logo instantly recognizable.
Boutique logos are usually stamped on clothing labels, tags, and displayed on billboards. This means that you must have a responsive logo design to rescale, resize, and a bit of adjustment according to the requirements of devices, screens and prints. It's also best if the logo works well in black-and-white as well as color.
There are several major boutiques that simply have their name as their logo, but this requires a suitable font. There might be some flourishes in a boutique logo font, but it should overall be easily readable. This is especially the case when viewed from a distance, as a boutique is likely to use billboards as an advertising medium.
The Bernhard Fashion BT font is acceptable for a boutique logo, as is the Calligrapher if you're going for a bolder look. Even high-end boutiques may have simple fonts that make a statement, so there's not much need for curly letters.
In order to choose the best elements for your boutique logo, don't ignore the perks of hiring a professional logo designer. An expert would be able to guide you best in order to decide upon the perfect logo.
