How to Choose the Best Shapewear for Tight Dress
1. Smooth and invisible
The first step is to make sure that the Spanx is smooth and invisible. Avoid shapewear with elastic bands because they will show lines. If the figure shaper is made of a lightweight material this is better because it will keep everything smooth.
2. Stays in place
Good Spanx should stay in place the whole day. It should have good compression so that it does not keep moving. If you are worried that your foundation garment will slide down or roll up, it is advisable to consider getting a bodysuit design.
3. Comfort and convenience
When wearing Spanx, comfort and convenience is everything. You need to make sure that you are comfortable by choosing a breathable material so that you do not sweat uncomfortably. Convenience is also important so you need to get Spanx with an open crotch so that your bathroom breaks are easy.
It’s advisable to get Spanx with a good stretch. Spanx with a good stretch will give you the freedom you need when wearing them. Make sure that it has stretchable spandex material or an equivalent so that it can still fit you whether you lose or gain weight.
5. Good quality fabric
Choose a good quality fabric for your Spanx body shaper. High-quality material will not irritate your skin and it will also last for a long time. Cheap Spanx shapewear does not last for a long time and in a matter of time they end up ripping apart or becoming too loose to wear.
FAQs on the best Spanx for tight dresses
Can you wear shapewear with a bodycon dress?
Yes. The best way to wear a bodycon dress is to wear a figure shaper underneath. Bodycon dresses can be very unforgiving since they show every imperfection on your body. Trust me, even supermodels with a perfect body need shapewear when wearing a bodycon dress. The work of shapewear is to balance and smooth your curves thus reducing creases on the dress.
Does shapewear reduce your dress size?
No, shapewear does not reduce your dress size. The role of shapewear is to help you achieve a smooth look by reducing the bumps on your body. It will smooth the fat roles and even cellulite on your thighs. If you decide to wear shapewear make sure that you still stick to your ideal dress size. You will achieve a beautiful look without even going a dress size lower.
How do you pee in Spanx?
First, for you to pee in any shapewear, it needs to have an open crotch or a gusset that can be opened. Otherwise, you would have to pull down the Spanx any time you want to relieve yourself.
If it has a pee hole, how do you pee without getting the Spanx wet? It’s easy. Open the gusset and tuck a piece of toilet paper into one side of the opening, letting the larger part of the tissue hang along your thigh. Repeat this on the opposite side of the pee hole.
Part the gusset with your hands so that there is enough space between the two pieces of toilet paper. Squat to pee and remove the tissue papers when you’re done.
Your bodycon dresses such as bridal gowns, dinner date dresses, or even modeling dresses, and the events associated with them don’t have to be just ordinary. Spanx shapewear can help you smooth out your curves and edges in these close-fitting outfits so that you look stunning and memorable.
