I agree with everyone else, unfortunately. It looks dated but I think it because of the colours.
Fisicx is right with the comments above.
Have a look at Holland & Barrett below, they are selling tons, probably have a whole load of Developers and Marketing Teams working on their site, so I'd look at what works with their site and use that as a bench mark for your site.
Aim to make your site easier to use, and take notice of these comparisons.

1) the first thing I see on your site is a big pink flower, the first thing I see on theirs is that they sell Health products and vitamins.
2) I see Love Your Well Ness, and a call to action, in the first couple of seconds I know what they are selling and a big green button that's asking me to click to shop
3) I know they do free delivery over £25 and they have a big 20% off the banner.
4) Your site I couldn't find the delivery details or the returns details. Even though its at the top of the page. It just doesn't stand out as well.
Have a look at this free downloadable template, and have fewer colours, it draws attention to your call to Action buttons and your products.

It's also a good idea to get honest feedback on a forum like this. I find if I ask friends and colleges they just tell me what I want to hear, they don't want to offend.
With strangers, they don't care about offending but do care about giving you honest advice that will help you find out what potential clients think, and ultimately make them buy from your site.
Good luck
