NO: to anything that is big. Oversized/heavy.
No to anything that is too small / too short.
No to bright colors / neon.
No wild prints/text/words/logos. Solid colors.
No to pastels, no to White/light clothing.
No to sleeveless clothing... but if you have to then only worn with skirts or dresses (to keep focus on your lower legs)
YES: Typically most 3/4 sleeve tops with v-necks and empire waist are the most flattering for women.
Yes to straight or wide leg dark colored jeans
Yes to flat fronted trousers (making sure that the zipper is on the side or at the back so it doesn't add more bulk to your tummy)
Yes to a pencil skirt
Yes to an a-line shift dress
Yes to a wrap dress
Yes to nude color shoes with heels (personally I'm not a fan of this look but it does make your legs look longer)
Yes to knee length heeled boots (if you can't manage a tall thin heel, you can go with a chunky or wedge)
Yes to shapewear bike shorts (or, the best undergarment shapewear support you can afford, I say bike shorts because they tend to be cheaper)
Yes to opaque stockings
Yes to jersey, cashmere, fine cotton, spandex, flat knits, fine ribs, wool, rayon.
Stick to dark colour hues for your "worst/biggest parts"
For hair, consider getting highlights / lowlights.
Consider cutting two to three inches below the collarbone but no longer and maybe no shorter (this will depend on your preferences your upkeep and the current length of your hair of course)
Consider long layers (less solid and chunky, more layered and long)
Consider side swept bangs (wispy, not thick)
If looking for swimsuit:
Black is best, or black bottoms with a brightly colored top.
Make sure it has body shaper compression /support
Empire/ raised waist draws attention upwards
V-neck is flattering and so are high cut legs (yeah I know I'm not comfortable with the high cut legs part either but it actually does make your legs look a lot longer)
Tankinis are not good. Go with a bikini (if you're comfortable with that, I'm not) or a one piece
A nice cover-up is essential (try to get one with an empire waist dress style)
Self tanner never hurts. (I'm not a fan of real tans, it's bad for your skin, but a little bit of darkness does make you look healthier / younger/thinner etc)
Winter: buy a coat with shape, structure, and fit
Go knee length but no longer (level with your butt is too short)
Make sure it is fitted at the waist and flares outward to the Hem
Pick a solid color, darker is better (you can always accessorize hat / scarf/mits with bright colors)
A "big" hat makes your face look smaller
Fancy dress:
Go simple, clean cuts.
Decent undergarment shapewear always!!
Knee length or full formal length dress to the floor
Not too much "shine" (ex jewelry)
For (the dreaded) photos:
Camera position from "slightly" above (it's better to have the camera angle just a little bit higher than you rather than lower, eliminates double chin, lumps etc)
No harsh lighting / shadows (which also make double chins, lumps etc)
Stand straight, shoulders back, chin up and out slightly.
Stand at a 3/4 turn towards the camera with one leg slightly in front of the other. Front foot out, back foot to the side and weight bearing.
Arms slightly out from your body and slightly bent at the elbows (not how flat against your body it makes them look fatter)
Lift your tongue to the roof of your mouth to tighten your chin muscles.
Hand placed on hip or in pocket (away from your body)
Stand in the middle of a group or in the back row not on the ends.
Okay that is literally everything that I know. And yes I actually do have all this stuff written out on paper thumbtacked in my closet to remind me whenever I need to purchase clothing or replace it, this is what I should be looking for. Personally, almost all of my clothing is purchased second hand / thrift stores and that means you have to do a lot of looking. There's a lot of days where you go in and you'll find nothing. But, you do get lucky. It's like a treasure hunt.
Mostly, don't be down on yourself. I know that's easy to say and I know that's hard to do especially when you're feeling so bad. To be honest this is advice that I should take more often myself. It's much easier to give support to others than it is to take it sometimes, isn't it?
Hope this helps 💜
