Visible Panty Line is a constant struggle because a lot of clothing items aren't lined anymore.  Lined meaning, there is an extra layer of material between you and the garment to avoid seeing any bumps, lumps or panty lines.  They also don't make slips anymore like they used to either.  The new thing is shape-wear which I am not a fan.  I think it's confining, constricting and uncomfortable.  The closest I get is control top panty hose when it gets cooler out for more dressy and formal occasions.   

For all the other times, wearing the right underwear is crucial. 

Fabrics:

• Cotton:  This is by far the best fabric to buy for your body.  It's also a great choice to wear under denim. 
• Satin/Silk:  This may feel silky and smooth but is not ideal for all day wear, unless it has a cotton panel.  Yeast infections are a very real thing.  
• Lace:  It's pretty and feminine but can be seen through almost anything.  I say keep this to lingerie unless that's the look you are going for. 
• Polyester/Rayon:  This fabric is becoming more and more common in place of satin or silk because it's cheaper to make and produce.  The same rules apply, if it doesn't come with a cotton panel, don't bother with them.  
• Lycra/Spandex:  It's tight.  It will stretch out faster no matter how well you wash it and it's more expensive.  You can wear this under formal dresses, semi formal wear, work clothing as well.  It doesn't breath well either, so pray there is a good A/C wherever you are going. 

Styles:

• Hipsters:  This is my favorite style to wear as far as every day is concerned.  It sits at the top of your hips, right below your belly button.  It's comfortable, trendy and can be worn with pants, skirts, and various short styles. I wouldn't recommend it under a dress because of the dreaded "roll down" then you have to pray you have a moment to run to the bathroom to adjust yourself. 
• Boy Shorts:  This is a fun style that a lot of people enjoy.  It can be worn under almost everything and is very comfortable.  It does allow for more coverage of your tushie and sits at your belly button.  
• Thong:  Be careful with this style.  It might be sexy but it's not ideal to wear all day.  
• High Waist:  This is great under dresses and dress pants.  It allows for the coverage, comfort and seamless effect.  

My rule of thumb is prepare your undergarments as well as you prepare the outfit you are wearing.  The right underwear can save you a lot of embarrassing situations in life, also can save you from doing that shuffle-walk in an effort to adjust yourself.  Invest in good quality underwear that will last a while for your formal and professional ocassions.  Do not feel like you are stuck buying from one store because there are a lot of retailers that sell plus size items.  Also, don't feel bad if you end up buying cheap, every day stuff either.  Things stretch out over time, get holes and don't fit as well as they did before.  Toss them, move on and be happy - your bottom half will thank you.  With each season, go through your drawer and discard.  You know what needs to stay and what needs to go.  

This is my faux pas with underwear done on purpose.  Yoga pants can be awesome but dangerous. Just be mindful of where your top is. That's my hip and part of my stomach.
