The biggest Valentine's Day fashion trends, according to an expert

While we have a few ideas for what we want to wear come Valentine's Day, we are always eager to hear from an expert on which trends we should try -- and which to avoid.

We caught up with celebrity fashion designer Katharine Polk, who has dressed all of our favorite celebs, including Kylie Jenner, Jennifer Lopez and Selena Gomez, to pick her brain on V-Day trends and tips. And as the founder & creative director at KRP Creative, we knew she wouldn't lead us astray. Check out all of her advice below!

The top do's and don’ts of Valentine’s Day dressing

"1.Be yourself. 2. Be comfortable. 3. Wear lingerie that fits. 4. Stay true to your style. 5. Don't try too hard. 6. Don't wear something too tight. 7. Don't dress for him or her. 8. Long and fitted or short and loose is my rule to live by when shopping and dressing!"

Hottest Valentine's style trends this year

"Delicate Chantilly lace tops and bias silk dresses [will be on trend this year]. Chantilly lace is great for layering and super sexy. You can show skin, but make sure to pair it with something less revealing like a gorgeous pair of silk pants. Find a beautiful bra to wear underneath that's meant to be seen and you’ll look stunning. For those who are looking for a slinky dress, the bias cut silk option is the way to go. For those of you who like to show some leg, I love a long sleeve dress with a high slit."

How to perfect classy, sultry and mystery all in one outfit

"I always live by the rule that you should keep your dress long and fitted or short and loose, but rarely short and tight. The key to classy is the long and fitted option. I suggest a beautiful silk mid-length dress or a lace midi paired with a silk trench for the ultimate mysterious, classy and sexy look."

"Another option for those ladies who love a shorter dress would be a beautiful silk draped wrap dress paired with some thigh-high suede boots. The key is to have the dress layer over your thigh high boots. Accessories can also make a huge difference to an outfit. To add a bit of class to your ensemble, natural diamonds are always a go-to accessory. Think simple diamond earrings or a classic diamond tennis bracelet."

Top trends for accessories this Valentine’s

"Hoops are the go-to accessory. A larger 2” hoop can be a little naughty and a smaller 3/4” hoop can read a bit classier. Either way, you should always have a set of hoops in various sizes for each mood! I love styling these with delicate gold and diamond stacked rings. The stacking ring is a must-have in every woman's jewelry box this season. They are so versatile and easy to style with any outfit -- both day and night.

Natural diamonds are always on trend and can put the finishing touch on any outfit. They're a lasting symbol of romance and elegance, making them perfect for Valentine's Day. You can't go wrong with diamond studs. Studs are a look that never go out of style and can look sexy and sophisticated no matter what you're wearing, whether it be a cocktail dress or a pair of jeans and a t-shirt."
