[Need advise]Dropshipping Woocommerce + Social Media

I'm going to create woocommerce store with dropshipping from aliexpress . I see some potencial to generate some money from dropshipping. My budget is 200 - 400€ -( I know create woocommerce site on my own and other thing) .I'm not total beginer in IM but I don't want to burn a lot of time and money . I spend almost 3 weeks about search right niche for DS I 'm worried about that.

1.Niche is jewellery - but not common from first page with maximum sales . I'd like to sell different bracelets, necklaces for woman (upsells for men). I want to sell products from 3.5 - 5$ for 1 item with 70%-120% margin . For advertising I want use first time - instagram with free traffic (follow/like method for profile) + paid ; then facebook ads maybe shoutouts from instagram . Target audience is women , men 18 - 40 years (start between 18 - 30 yo) with interest of shopping and beauty , Europe - english speaking countries gradually UK,IRL , Austria , Sweden maybe Denmark.

I am worries about ads - cost for lead/sale maybe little bit of saturation of jewellery. But mainly if is good stuff to choose for dropshipping due low cost of items and high cost for lead . My goal is gradually generate about 30-100€ per day .

2.Niche is gadgets , house decor (lights , air diffusers ....)
3.Niche is interested socks with interesting desings


For all niches are target countries EU . I'd like to choose 1 niche because jewellery is something what I 'm interesting for and I like it . But I 'm also open to choose other niches.

Thank you for any advise.

I dont see why not

that will be the main problem, ads - and as you said: saturation of jewellery

due to saturation I want to use instead of common shopify model - woocommerce - where I want to more trustable site with privacy , shipping options , tracking , also with attractive content of photos and text and many more .... All model of website I want to boost with social media (FB+IG) making competitions ,discounts work with emails...
