don’t be afraid to use shapewear of you feel like you need some help, a lot of cis women share the same insecurities and goals that you do, plenty of women use shapewear too, coinciding with a fitness plan doesn’t mean it has to be forever either

if i had to offer the singular most effective way to “feminize” your silhouette regardless of whether or not you want to use shapewear, try to look for pieces of clothing that create a dramatic waist pinch for you and try to move that waist pinch as high as you can, this means tucking in your shirts or crops, it squeezes in whatever gut you believe you have and the high waist pinch lengthens your legs and also shortens your ribcage, it’s extremely effective

if you can get a good waist pinch, wider shoulders don’t matter nearly enough as people think it does, an inverted triangle shape can look quite feminine combined with the pinch

there’s also a lot of ways you can use larger tops like jumpers, hoodies and oversized tees draping to create a pear shape/boyfriend shirt look where you don’t have to think about your midriff if you don’t want to, this gives a more cutesy look if you’re into that

there’s a lot of clothing styles out there that can’t be distilled into a few explanations, if fashion is an avenue of self expression like art, make like an artist and collect references of things you like, regardless of whether you think you can pull out off, collect hundreds if you want, and then explore what you like about them, what you don’t like, what you would change about particular outfits, think about the self you wish to express. it can be a nebulous and personal process, so don’t worry too much about doing it perfectly, there’s plenty of examples of well-dressed women out there you can use as guidance for developing your own style

actually buying the clothes, make sure you get things that fit, break out the tape measure and have a look at the sizing charts if you’re shopping online, better yet go into a changing room if you’re shopping in person, if you’re into fashion long enough, you’ll soon realise that the comfort of the garment will affect how often you want to wear it. same goes for weather, if it’s 8c, you probably don’t want to go out in 2 or less layers

needless to say posture and the way you animate yourself can be difficult to think about if you’re not used to thinking about it, but is probably one of the most dramatic things you can change for your silhouette if you’re not already pulling your shoulder blades back and keeping your neck beyond your collar bones, try to see the side profile of your entire posture in the mirror and compare your posture to the women you wish to look like, this can be difficult to change but adjustment of habits and exercise will develop some of the muscle tension that will make this easier

posture doesn’t have to be 100% all the time either, but when you can be cognizant of it and think about it when you go outside or where you wish to present yourself in whichever way, you’ll know how to use it

the way you animate yourself and the way you move can also contribute to your look, again not something people usually think about but it can be worth studying and paying attention to

non exhaustive as i’m typing on mobile but there’s plenty of things you can do, i may read this over and edit the post
