Sunday marked the first day of spring, meaning it’s time to break out the allergy medicine and sundresses. It’s also a tempting time. I know when you see those crocuses blooming, a little voice in your brain nags you to put on shorts and sandals.

Do me a favor. Those warm-weather-loving whispers that pester you to buy every bikini in the store? Shut them up. It might be spring, but spring doesn’t necessarily equal warmth, sunshine and daisies. Don’t worry, though; those days are on the way.

Spring means layers. I know you’re chomping at the bit to hide all those bulky coats and say goodbye to the winter blues, but spring is a transitional season.

Early mornings and evenings will make you want to wrap yourself in a sweater, and afternoons will make you feel like melting.

I repeat: Dress in layers. I’m sure your mothers have said it, and in our pigheadedness we’ve ignored their sage wisdom. Start listening, kiddos. Mama knows what’s up.

To dress in layers without looking like you’ve gained 10 pounds, wear lightweight garments. Try combos like a fitted camisole with a flowy pullover, an oversized jumper over a tight turtleneck, or a pair of chinos and breezy boho tunic.

Dressing in layers — and dressing in general — is all about getting the right proportions.

Want to start wearing your summer duds? You can! Just be smart about it. Layer a sleeveless sundress with a denim jacket, flats and perhaps a light scarf — nothing too wooly.

If that outfit is a little too 1950s housewife for you, jeans and a button-down shirt are always stylish. Add a pair of ankle boots and an oversized boyfriend sweater, and you’ll be the snazziest gal about town.

Overalls are another fun spring look. Scout thrift shops for throwback finds like the cute corduroy pair I recently found at Goodwill. Roll up the ankles, slip into loafers and a turtleneck, and you’ll look like you just stepped out of an ad for Ralph Lauren.

Listen to your mothers and me: dress in layers. Happy spring!
