Quick answer

Choose your usual back size and current cup size for a firm, supportive fit, and treat the Crystal bra as a leakproof layer that replaces breast pads rather than as a bra you size up for comfort.

Why the Crystal bra is designed to feel firm, not loose

The Maternity Bra (Leakproof) in Crystal is built with a firm fit to give extra support and shape, particularly for a fuller cup. That is a deliberate design choice: a looser band would let the absorbent layer shift away from the nipple, which is exactly where leaks start. If you are used to relaxing into a softer everyday bra, expect the first wear to feel more secure and less stretchy. Give yourself a minute to adjust the straps and back fastening before deciding it is too tight.

When sizing help matters most

Sizing is the one area where the Crystal bra gives you little room to guess. Because the bra combines a waterproof outer layer with an absorbent inner layer, the cup needs to sit flat against your breast rather than gaping or folding. If you are between band sizes, start with the smaller band and use the adjustable fastening; if your cup size has changed significantly since pregnancy, re-measure before ordering. The product page lists back size and cup size as the available options, so use those two measurements rather than a generic small, medium, large scale.

What the leakproof layer does and does not replace

The Crystal bra’s Dry Layer absorbs breast milk and the waterproof outer layer stops leaks from passing through, so you do not need to add disposable breast pads. That is a real convenience, but it does not make the bra waterproof against heavy let-down or overnight flooding. Think of it as your daytime leakproof option: it handles the everyday leaks that stain tops, while you may still want a different setup for long stretches without a change. The bra is not described as a pumping bra, so do not expect flanges or hands-free pumping features.

Caring for the Crystal bra without damaging the leakproof layers

The absorbent and waterproof layers are the reason this bra works, so care instructions matter more than they do for an ordinary lace bra. The catalog does not list a full washing specification, so follow the care label inside the bra rather than guessing. As a practical rule, avoid fabric softener and high heat, which can coat or distort technical layers; a cool, gentle wash and air drying are the safest default until the label tells you otherwise. The scalloped lace also benefits from a lingerie bag to stop it catching on fastenings.

Crystal maternity bra questions, answered

How should the Crystal bra fit?

The band should feel firm and stay level around your ribcage, and the lace cups should lie flat without gaping or digging in. The bra is designed for a firm fit, so a little initial snugness is expected; if the band rides up or the cups crease, try a different back or cup size. Check the band first: if it lifts when you raise your arms, the back size is too large.

Do I still need breast pads with this bra?

No for everyday leaks: the Dry Layer absorbs milk and the waterproof outer layer stops it reaching your clothes. For heavy let-down or overnight use, keep a separate absorbent option, because the bra is not described as unlimited-capacity. Use the Crystal bra as your daytime leakproof layer and reassess for nights.

How do I choose between back size and cup size?

Use your current underbust measurement for back size and your current bust measurement for cup size, taken while wearing a non-padded bra. If you are between back sizes, choose the smaller one and use the adjustable fastening; if your cup has changed since pregnancy, re-measure rather than relying on your pre-pregnancy size. Measure now, not before pregnancy, because cup size is the most likely thing to have changed.

Can I wash it normally?

The catalog does not provide a full wash specification, so check the care label first. Until then, wash cool and gentle, skip fabric softener, and air dry; use a lingerie bag to protect the scalloped lace. Heat and softener are the two things most likely to reduce the leakproof performance.

Is it a nursing bra or a pumping bra?

It is a maternity bra with leakproof features, designed with input from real mums on nursing challenges. The catalog does not describe pumping flanges or hands-free pumping, so treat it as a nursing and leakproof bra rather than a pump accessory. If you need hands-free pumping, this bra is not positioned for that job.
