Undergarments for under a mermaid dress?

Try Shapermint or HoneyLove

You should find what you need if you search "mermaid dress slip". They have layers of tulle that add volume only to the bottom portion so your dress will maintain its shape better. I don't know what brands are good though, sorry.

Whatever you end up getting, just be sure it's comfortable! Then it won't become a distraction and you can focus on the best parts of the day

Do you need a slip or just shapewear? I packed myself in like a sausage with a longline low back bra and a pair of bike short-style spanx. Everything was smooth and secure and I felt suuuuuper supported.

What kinds of pieces are you looking for?

View Quoted Comment I am looking for something to definitely be comfortable. Definitely looking for shape wear just to kept things in tact and the right shape. My dress is a strapless mermaid dress.

I had the same, and def highly recommend high waisted mid-thigh shorts! Lots of brands make them, I've even bought some off Amazon a few times
