Tips and suggestion

Hello male 18 here. I ask of you to not judge too hard, as i am not sure myself.

Intro: Good evening everyone, or whatever time it is for you. I have tried a few subreddits, and now I have come here. I will try to keep things brief.

Context: Most of the time, I like to be masculine (as i work out) but once in a while i feel very femenine and would like to dress so.

Desire: As this is only once in a while I would like to get clothes that are kinda cute, but could also be used in a more "masculine" style. I am already thinking of a sleeveless turtleneck, but couldnt find many online. The reason I am looking online is because, the fashion sense where i live is rather repetitious and unexciting.

Also if you have any suggestions (or wanna discuss things) for workouts, I am open for such matters too. My focuses at the time are back and legs.

Question/summary: Are there any clothing you would suggest for me? Any QUALITY online stores you would recommend? (not high fashion, but also not temu, ebay or similar) Lastly, any workout tips?

All comments welcome. Thank you for your time.
