Jene Luciani Sena is a bra expert. No, really. She’s a contributor to Retailmenot, founder of the Grem Bra, and author of the must-read fashion book: The Bra Book--an intimate guide to finding the right bra, shapewear, swimsuit and more!--published by BenBella Books.

Truth bomb: Finding the right bra is complicated. The straps have to fit well, and if you go strapless your boobies have to work extra hard to keep the bra supported. Plus, the wrong bra can make your outfit just look bulky, wrinkled, or even just…wrong. Not to mention, some teens prefer padding, some don’t…bra shopping can be chaos. But it doesn’t have to be.

This book is like having your own personal shopper and it’s great for teens as well as adult women. Some of the easy-to-understand topics Jene covers (put intended!) in The Bra Book include: checking for fit, bra styles, fabrics, advice when bra shopping inside a store, and so much more. She even digs deep into the interesting fashion history of the bra.

If you think about it, the right bra really does pull your whole outfit together. That’s why you should find one—or a few—you really love that pull your outfits together.
