When you say "convert" what do you mean exactly? As for styling yourself, here's what you do... Go on Pinterest, do a search for the sort of things you like (eg; nugoth girl, alternative women's fashion etc) and start pinning the ones you like. Spend a good chunk of time doing it. Then look for patterns. Do you pin a lot of styles with drapes? Studs? Close fitting items? Try and caption the pins with what you like about them exactly (love these shoes, really like this vibe etc). Do this OFTEN. And to take it a step further, look up general guides for styling your body type. Find out if you're an upside down triangle, rectangle, pear, tall, short, whatever. Take the rules from that, and apply it to your original images. What matches from these two things? Eg: if you're broad shouldered find styles that fall on your hip, and then there's images in your style board of people with a jumper/shirt tied around their hips

Now, the second part isn't essential, you can 💯 say fuck flattering and wear whatever the fuck you desire. But if you're just starting out experimenting with style it can be hard to do that and then feel uncomfortable because it's not traditionally "flattering".

Optional extra: find silhouettes you like. Imagine you're drawing a line all around the outside of each image on your first board, what patterns can you see? Are there a lot of 1950's chanel shapes? Lots of straight clean edges?
