If you have a more casual jacket like a denim jacket you can be a bit more adventurous. Wear a cluster of pins like Michael Jackson badges, One Direction badges, Peace badges, Save the Whales badges etc on the chest or sleeves of the jacket and add a vintage bird brooch as a 'surprise touch' - it's a great way to let your personlity shine through and your love of diverse things.
You can also wear a vintage brooch on your top - usually near the top on one side. If your top has ties on it however you can use a vintage pin on them whether they're at the botton in the front or on the side.
Gloves can also rock the vintage pin look really well. I can't take any credit for this idea as it's from a future fashionista extroidinaire aka my tween age daughter. She wore a pair of short 'fake biker' style black gloves a la Lady Gaga and she popped a brooch on one of them. The look was pretty cool and the contrast between a very trendy fashion glove and a piece of vintage jewelry gives an outfit a very unique feel.
Bags also look great with a brooch added, particularly a clutch purse when you're going out in the evening.
Some wristbands can have brooches added to them depending on the material they're made with. My daughter has a cool thin denim band which looks great by itself, but rises to a whole new level with a brooch added. My daughter and her cousins also have some crocheted wristbands that my sister-in-law made and they can acquire a totally different look depending on the pin added.
When it comes to famous people wearing vintage brooches you can get even more ideas on how to add them to your wardrobe such as on the hip of your evening dress (obviously this depends on your figure!).
Michelle Obama wears a lot of different brooches and she pops them in the V of a V-neck top as well as combining a group of them to add 'bling' to a round necked top. She has also worn brooches at her waist.
I'm sure there are many more great ways to add a vintage brooch to your wardrobe if you just use your imagination. Be sure to let me know any other ideas in the comments, but first here are a few more vintage bird pins.
