Crossover Maternity Bikini Underwear, 6-pk, Inspiration

Go for it, buy these. I am such a prude w spending on maternity things, but these are splendid, and that's coming from a pregnant girl that literally hates anything and everything. I can't speak for the lace ones, but I don't even remember I'm wearing these, which is a huge win.
So since no one is specific w reviews, I'll help you out as much as I can and be the opposite. I'm 5' 7". Pre pregnancy--27 waist, 36 hips, 125 lbs. I'm on month 7 now and have gained 22 lbs... got the M and they are perfect after being washed and dried.
I got the XL for my pregnancy pal who is 5' 9" with a healthy rear and thighs, pregnant w twins. She says they "fit if she doesn't dry them." :-/

I love these. Super comfortable. They do run smaller. Im usually a medium but large works perfectly for me. Love the material, I prefer cotton so these were perfect.

These were amazing throughout my pregnancy! Even though they sit very low, they stay in place well and because of this, you can get away with using the same size throughout your pregnancy, despite an ever growing bump. Additionally, the white liner comes in very handy to keep an eye on any changes down there, which is very practical, and they hold up nicely after loads of washes.

I purchased my size after following the sizing instructions, and they fit as expected. As my pregnancy has gone on, these have become part of my daily wardrobe, and I have bought additional sets. I like how they sit below my bump and stay in place.

My daughter said they fit perfectly and are very comfortable.
