a LOT of abandoned checkouts on shopify clothing brand

Hey nice to meet you guys

I have a new clothing brand and I have been running fb ads on it, honestly we are averaging around 3k a month right now but barely profitable due to a lot of abandoned checkouts. Like i spend around 50-75$ a day and get around 2-3% CTR, 3-5 checkouts initiated a day but a lot or almost all of them are abandoned for some reason.

Its not like we are selling expensive clothes either, most of our clothes are around $50-80 range with $10-$15 shipping. So I don't think the high shipping cost is the problem in this scenario.

What do you think the issue is? And what could I do to improve conversions? This exact store layout/theme has gotten over 10k a month for other brands so I don't think the theme is the issue but lately its just weird almost to the point that I have been thinking its my payment processor thats not working but thats not the case either.

If anyone experienced this or knows how to improve this, I would appreciate any feedback. Thank you!!
