It's tempting to buy a bunch of tees in a new fit, but avoid these pitfalls:

• Buying without trying: Fit varies by brand. Even if you love one oversized tee, another brand's version might fit differently. Order from places with easy returns.
• Chasing trends: Oversized is popular now, but it's not for everyone. If you feel lost in your clothes, that's not style—it's frustration.
• Ignoring fabric quality: A cheap oversized tee can look like a rag after a few washes. Invest in good cotton or blends that hold shape.
• Forgetting your wardrobe: An oversized tee won't suddenly make your regular-fit jeans look better. Consider how each piece works with what you already own.
