Lingerie: Sizes, Fabrics, and What to Look for Before Buying

Size: band and cup size, not a letter

A bra size consists of two numbers: the band size (80, 85, 90…) and the cup size (A, B, C…). An 85B is not the same as a 90A. If you’re unsure between two band sizes, measure the circumference under your bust and add the value indicated in the store’s size chart; this is usually more reliable than a T-shirt size.

For panties and bodysuits, the size is based on your pants size, but the stretchy fabric is less forgiving than it seems: if you’re between sizes, go with the larger one. And always check the size chart for that specific store—two brands may have the same size labels but different cuts.

Fabrics: What Holds Up and What Doesn't

Lace with more than 5% spandex recovers its shape; with less than that, it stretches and stays stretched. Tulle is beautiful but delicate: it snags on fingernails and Velcro. Microfiber holds up best to daily wear and washing. Satin adds shine, but it shows through more on the clothing underneath.

Check the ingredients list on the product page—don't just look at the photo. If it's not listed, that's a red flag: a store that doesn't list the ingredients usually doesn't list the sizes accurately either.

What to Look for on the Form

• Composition and percentage of elastane.
• That store's size chart—not the generic one.
• If the listing specifies size and color: On Glim, the size is listed in the description itself, not in the title.
• Closure (hooks and eyes, clasps, tie) and whether the cup has underwire or not.
• Return Policy: Underwear is generally excluded for hygiene reasons.

Returns: What Almost No One Reads

Many stores do not accept returns on underwear for hygiene reasons, although the law allows for exceptions if you are informed of this before making a purchase. Check the product description or the terms and conditions before ordering, especially if you're unsure about the size. If the store doesn't state this clearly, assume that returns are not accepted.

How We Display It in Glim

When a store provides size and color information in its feed, the listing displays them alongside the price. If the store doesn't provide that information, we don't make it up: you'll see the product without size information and will have to check it at the store. That's the difference between comparing based on data and filling in the gaps.
