🤔 FAQs
Got a few more questions? I’ve got you covered. Here are the answers to some of the most common queries about this wardrobe staple.
1. I’m petite! Can I really pull off an oversized blazer?
Absolutely! The secret is all in the fit, not the label.
Make sure the shoulder seams sit correctly on your actual shoulders. As long as the shoulders fit, the “oversized” drape will look intentional and chic, not like you’re swimming in it.
2. What’s the difference between ‘oversized’ and just buying a blazer that’s too big?
Great question! An “oversized” blazer is designed to be roomy with a relaxed silhouette, but it’s still made in your actual size.
A blazer that’s simply too big will have ill-fitting shoulders that droop down your arms, which is the main thing to avoid.
3. What are the best shoes to wear with an oversized blazer?
You have so many options! It really depends on the vibe you’re going for.
For a casual, classic look, go for leather loafers or clean, minimalist sneakers. To dress it up for the evening, a pair of heels or sleek ankle boots works perfectly.
4. Are oversized blazers still a trend for Autumn/Winter 2025?
Yes, 100%! The oversized blazer is more of a modern staple than a fleeting trend at this point.
It was all over the A/W 2025 runways and continues to be a key piece for achieving that effortless, layered European look.
5. How do I take care of my blazer so it lasts?
Always check the care label first, as different fabrics need different care.
For most wool or structured blazers, professional dry cleaning is the safest bet. For minor spills, spot cleaning with a damp cloth can work wonders!
