Need advice on this

I have recently done work on this website Hidden Pearls. Basically the website was really broken from functionality point of view like its menu couldn't be even be open on mobile browser. It would just shut itself lol. I have now designed separate headers including menus for mobile and desktop. Their majority of customers are on mobile website. However I don't have much knowledge of UX stuff for E-commerce websites. If it helps, their target market are women in their 30s. Another thing that i have advised them to change is their All-Caps menu to lower case because of legibility. So if you experts could critique the website for any minor changes that could improve it from a UX perspective, that would be great! Thank you!!
