With spring around the corner, you'll soon be shedding your bulky sweaters and breaking out your tank tops. And with less fabric for many spring fashions, the right bra is essential.

But how do you know you have the right bra?

On "The Early Show," supermodel and Victoria's Secret angel Adriana Lima shared common mistakes women make with their bras and tips for picking the right bra, so you'll know when a bra works -- and doesn't.

T-shirt problem: Seams and/or lumps
Solution: Smooth seamless bra

Why: For a smooth fit, never wear a lacy bra. If your shirt is tight, you may show spillover bumps from the top of your bra so make sure you wear the right size bra. Also, if you're wearing white or a light color, wear a nude-colored bra that closely matches your skin to keep it hidden. Even white bras can show through a white blouse.

Tank top problem: Sloppy straps
Solution: Racerback

Why: Consider racer back or cross back bras to wear. You can rest assured that your bra straps won't slip into view.

Halter problem: Back straps
Solution: Multi-way

Why: The multi-way bra goes around neck, so strap hooks at front so you have support, but no straps showing.

Strapless problem: Sagging
Solution: Molded strapless bra

Why: Strapless bras tend to head south. By the end of the day you don't want it around your midsection. A racerback will be strong enough to hold the bra in place without flattening the bust.

Additional notes: Every woman should own a strapless bra. With off-the-shoulder dresses and tops, they are an absolute must. Support is the most important factor. You want to make sure the strapless bra holds you in completely, lifts your breasts, stays in place and does not leave indentations in your skin. It should also be comfortable and wear well throughout an entire day or for evening out. Smaller chests can get away with a stretch tube bra, while larger chests may still need the support of a more constructed bra that hooks in the back.
