Fit
- Size Chart
- In pregnancy and postpartum, cup size fluctuates a lot, so owning 2 sizes can be helpful. We recommend going with your regular size and one size up for your fuller days. Plus with all the washing and wearing, owning 2 comes in handy - trust us.
- Preference also plays a role - if you prefer more cup coverage and a roomier band, you might consider sizing up
- Wide plush elastic band for extra comfort + support
- Adjustable straps and hook & eye closure in the back
- Wireless
Fabric + Care
- Belgian stretch nylon is buttery smooth and wispy thin
- For the early days of breastfeeding, we recommend getting 100% cotton inserts to absorb leakage — we love the ones from TL Care!
- 75% Polyamide (Nylon) 25% Elastane (Spandex)
- Wash on cold/delicate, dry flat

* Non-wire bra sizing can vary by preference and if you're toward the top of a size range and prefer more coverage, you may want to size up. For styles available in + sizes (designed with additional support details for our larger cup customers), we find DD's can be on the cusp - if you prefer more coverage and support, we suggest the + bra equivalent for your band size.
Btw, the size nomenclature has changed for Bra Tops. Here's the conversion:
XS=0, S=1, M=2, L=3, XL=4, XXL=5

I purchased both a negative and a Blanqi maternity nursing bra. Hands down I love the negative nursing bra. I found the blanqi bra itchy with the extra strap inside the bra that was much too long and seems unnecessary. I have not started breast feeding yet, baby's due in January, but the negative seems easy to unhook and is much more comfortable. I typically wear a 34 D and purchased a size 2 that I returned for a 3 since it seemed like it was going to be to small for me pretty quickly.
