Looking for a perfect way to keep your confidence high during the holidays? Are you planning a seaside resort getaway with your lover? If so Yummie Tummie is the ideal item to pack. Come on now, it’s not what you slip on on the outside, it’s what you put on beneath—and it’s as fashionable as it is functional.

Just an FYI, Yummie Tummie is like a t-shirt on steroids per Heather Thompson, designer and founder. “From the boardroom to bedroom it creates an hour glass figure while giving you the extra coverage and confidence you deserve,” says Thompson. The tops are created with a patent-pending dual fabric technology with a same-tone, firm control midsection panel that smoothes and shapes your stomach, hips, eliminating pounds and camouflaging lumps and bumps.

Thompson now boasts her holiday collection, with a strong focus on resort season wear. She points to the apparel offerings like her tube top or leopard print tank, which was recently worn behind the scenes by Beyonce at her show in Las Vegas. These look fierce over jeans or with leggings, and it’ll give you curves in all the right places.

There are so many styles and cuts; you just have to peruse their collection online at Yummietummie.com.
