Ever wondered how Hollywood stars get on the A-list and some pretenders never get anywhere? It all comes down to style. What makes an A-list different from a D list is how well stars carry themselves. Looking fashionably good is a must.

Today we will list four fashion blunders that D-listers make and how you can avoid them.

Blunder #1: Wearing the wrong lingerie.

Ever see that actress/model (read: starlet) on TV? You know the one wearing a tight white dress with the black lingerie showing underneath? People who wear the wrong kind of lingerie leave nothing to the imagination. The black lingerie under a white or light colored outfit is a common blunder. Remember: when wearing light-colored outfits, nude, beige and cream lingerie are musts. White lingerie under white dresses will still show through. Want an idea of how nude lingerie should look like? Brands like Le Mystere and Fantasie of England offer various bras in nude colors. The trick to wearing a nude-colored bra is wearing one closest to your skin tone. Wear a matching thong too!

Blunder #2: Having your "home base" exposed.

Day dresses tend to be on the gauzy side nowadays. Sheer is the way to go with sun dresses, wraps and even blouses. Even with fall settling nicely around us, the gauzy fabrics are still in fashion. So what do you do when your lumps and bumps are exposed against the light? Your sheer sexy dress becomes a see through dress. Think Barbara Streisand when she received her Oscar for "Funny Girl".

Not pretty.

To avoid this, instead of wearing the usual lingerie, try using shapewear. Shapewear not only smoothens out your silhouette. This also protects your "home base" showing through different kinds of lights. Great shapewear can be found at Ardyss Body Shapers and at Slim Powernet Body Shapers. Not only will you look sleeker, but also embarrassing see-through moments will be banished forever.

Blunder #3: Underarm Cleavage

"What?" You ask. Underarm cleavage is what you see when your breasts squeeze against your underarms. This usually happens when you are wearing an ill-fitting bra. Avoiding this is simple. Wear the right type and size of bra. A great way to avoid this: you can try a long line bra like Glamorise Front Close Posture Back Support Long Line for a smooth and comfortable day. Or you can try bras that have microfiber that molds perfectly to your breasts. Le Mystere Dream Tisha bra has microfiber that prevents slipping and is easy to adjust.

Blunder #4: Visible Nipples, the Mother of all Blunders

How many times have you walked out the door or dived into the pool only to be put down by your nipples showing through? Hollywood stars have actually discovered a great way to avoid nipple trouble. And now, you can avoid this by using nipple covers. Nippits are one of the most popular nipple covers on the market. These are adhesive, waterproof and hypoallergenic. These come in nude shades and aren't visible at all.

Are you ready to be on the A-list? Looking the part helps enormously.
