Reviews
runs small
"This ran small, sizing was not accurate"
Poor quality and unflattering fit
"While these underwear are soft and fairly comfortable, the elastic trim on this style is too tight and creates a really lumpy and unflattering fit. The quality is also pretty bad. I bought a five pack and within six months, the elastic waist band on two of the five pairs has unraveled and come detached. Really disappointing!"
They felt a bit small
"They felt a bit small compe to flex briefs and they were digging and giving me double but cheeks. And I have orders size bigger than my usual. They are really comfortable though and I will wear them I just don’t like my lines showing that much"
Recommend
"Fit comfortably and great match to my core plunge wireless bra which is a must! Great under whites."
Seams
"I really like this underwear my only gripe is the seam shows when wearing tighter athletic wear"
Love it!
"Quality materials and the fit is true to size."
Truly perfect underwear
"Upgraded to having a full set of quality, matching underwear as an adult (finally) and I’m glad I went with organic basics! The core brief fits well, the fabric is soft but durable, no loose threads, and the thigh openings don’t feel extremely tight, unlike some other brands I’ve had. Went with my normal Medium and fits well on a 31-32” waist. I bought the five-pack of this and now want more!"
The Perfect Pair
"Best fabric ever, OMG! I wish Organic Basics had multiple items in this exact fabric. It's taken so long to find good, simple underwear with non-toxic dyes. I'm really happy with these. A much better price point than brands that sell them for $30 a pair. (!)"
Great!
"Very comfy! Feels good to have organic undergarments especially after years of wearing synthetic. I feel like my body can breathe."
