Looking to increase conversion rate for online swimwear store

I'm looking to increase our conversion rate for our online swimwear store using shopify. We have been in business for about 8 years now but our conversion rate is not very high. On average for the last 12 months it is 0.84%. It is also a bit lower than this currently which is concerning. Our business is fairly seasonal so the conversion rate in the summer months (May - August) is a bit higher at 0.94%. We are a very international business, we are based in the UK but ship a lot to the US, Europe, Australia etc.

I am looking to achieve a more healthy conversion rate and would like some help analysing our website with some recommendations to approve this, plus some assistance with A/B testing etc. I can share google analytics information and of course it will be useful to look at the conversion rate breakdown throughout the checkout process to see where customers drop off etc.

We do a lot of paid ads and have this covered, I don't need any help with this. We achieve a lot of traffic per month from this, and work with instagram influencers etc but our conversion rate is not as high as it could be so I think some changes on our website are needed.
