The site has a clean and minimalistic look and feel and the presentation of the brand/fashion designer seems well done. However, there seems to be some inconsistencies of the UI.

The second thing (after the e-mail signup) that caught my eyes was the 10px letter-spaced logo with Times New Roman typeface. That is not really the best way to present it, because the spacing is not 100% consistent on all devices/viewports - that can be seen with the font-size and letter-spacing change on different media queries.

Also the logo does not seem to match with the overall branding (headings) of the site. You are using Playfair Display for the headings and Hind Guntur for the content. I am also missing consistencies with the overall headings. You have different font-weights and sizes across various different headings and some are uppercased, others are not. The content part seems pretty consistent.

For the UX part - that image change does not seem to work on the product details page and I get the Magento error: There has been an error processing your request, when I try to remove an item from the cart.

Liked the overall presentation of the products.

That is bad UX to ask your users to subscribe first before entering the website. Users dont even know what the website is about and you are already asking them to subscribe.

Collections tab is not working.

From what it looks to be a high fashion brand seems to lack the omph factor of being a high fashion brand. The homepage could be further improved in displaying what this brand has to offer. At first glace I thought this site is like a fashion show event. Some of the text in the home page is not noticeable and I didnt understand what I was looking at.

Not very nice to welcome your users with a "Sign up to our updates" modal ;) It looks cheap for what seems to be a high fashion brand.

The visual design is pretty well done, I like the fonts, everything shows that the user is in a high-fashion brand site.

The things that can be improved:
- The way the pages are transitioning is weird : I click on something, it loads (a fair amount of time) on the same page, then a loader appears, and finally the new page... I feel like the loader should appear immediately after I clicked on something.
- Some pages takes a lot of loading. I know that your contents are the kings, but I'm sure your images can be better compressed (Photoshop does magic with that :) )
- On certain devices, the right part of the menu is stuck to the logo, and that doesn't look good
- The menu item "The label" has only 1 sub-item... That's not good IA
- On big screens, the collections sub menu feels empty
- There should be more animations and micro-interaction, everything feels static

That's a good start, and the site doesn't fail to communicate on the quality of its products.
