The trick is in knowing what clothes to wear, what colors to chose from, and what accessories to wear. When choosing your wardrobe, the whole cliche about "black covering up fat" isn't necessarily true.
If you look good in dark colors, awesome. Don't listen to me! However, choosing the same colors for jackets and pants that are the same hue is also a really good idea as well because you aren't sectioning off areas. It's all ONE area which makes you look sinner. You can also wear blouses in a contrasting color as well if you needed to add a flair of drama to the outfit.
When choosing colors and pattern think vertical not horizontal. Bold buttons down the jacket or shirt, a long necklace, vertical stripes – these are all ways to think vertical and they can help tremendously! It's also important to wear colors that you feel good in.
Don't like red? Don't wear it! Love blue? Slap it on or add accents such as a shirt, or a necklace or a scarf. You can always tie in colors, you don't necessarily have to have "loud" colors on in order to look better. In fact, I prefer not to wear loud colors.
I stay away from pink, oranges and yellows at all cost! There is one thing that a lot of plus sized women do – they don't wear the right sizes. If you are an eighteen don't try fitting into a sixteen! All this ends up doing is accentuating those areas where you don't want it to accentuate!
For example, if you don't like your butt, and you buy a really tight pair of jeans, chances are your butt is going to look larger, so if this is something you want to avoid, then don't wear tight jeans! Same goes with shirts or dresses as well! If you are out shopping someplace and you aren't sure about a specific size or outfit or piece of clothing – ask the sales girl.
These girls are more than likely willing to give their advice about any fashion tips you need. Been there done that myself! You could also take a friend along with you as well if you are too embarrassed to ask a sales person to give you advice.
Most friends will be brutally honest about how you look, some are not. If you have a variety of friends pick the honest one! Also, if you like wearing jewelry, try to follow the "wear the right size" cliche above.
Don't wear tiny little earrings or necklaces. Try wearing things like chunky bracelets like bangles, or long flowing necklaces! So you see just because you are a plus sized woman doesn't mean you have to feel embarrassed or "out of place". I believe that all women are equally attractive in their own ways.
And a lot of people are going to look past the outside, and see the inside. This is what I try to remind myself when I'm having a bad hair day or something of the likes. If they don't look inside and all they care about is your looks? It's not a person you would want to have in your life anyway. YOU are beautiful just the way you are and don't let anyone tell you otherwise!
