Formal Dress Size Calculator Women's

Retail stores use vanity sizing to make shoppers feel better about buying smaller tags. High-end designers and formalwear brands stick strictly to true, historical couture measurements, which run significantly smaller.

Usually, no. Factory-made gowns only leave about a quarter-inch of extra fabric in the seams. Taking a dress in is routine for a tailor; letting it out is often impossible. Always size up if you are unsure.

We highly advise against this. Eveningwear takes weeks to ship, and ordering a dress that doesn't fit adds massive stress to your event prep. Buy the dress that fits your body today. If you drop a few pounds, a tailor can easily take it in.

Go with the larger size. A seamstress can flawlessly tailor a gown down one or two sizes to contour to your body. If you squeeze into the smaller size, you risk breaking the zipper or ruining the delicate fabric.

Only if you plan to wear that exact bra with the dress. If the gown features an open back or built-in bust cups and you intend to go braless, you should take your measurements without wearing a bra.

Almost every formal gown requires some level of tailoring. Depending on the complexity—like heavy beading or intricate lace—a standard hem and taking in the sides typically ranges between $50 and $150. Always budget for this!

The "hollow" is the small dip at the base of your neck, between your collarbones. This measurement drops straight down to where you want the hem to hit the floor. Remember to measure this while wearing your event shoes!

While the measurement math is the same, many curve and plus-size gowns feature structural benefits like corset backs. A lace-up corset is incredible because it allows for a highly adjustable, custom fit through the bust and waist without needing a tailor.

Generally, no. Most mass-produced formal gowns only have about 1/4 to 1/2 inch of seam allowance built inside the dress. It is incredibly difficult, expensive, and sometimes impossible to make a dress larger. This is why you should always size up and have a tailor take it in.

Absolutely not. We strongly advise against this. Formal dresses often take 6 to 8 weeks to ship. Ordering a smaller dress adds immense, unnecessary stress to your event prep. Order a dress that fits the beautiful body you have right now. If you happen to lose weight, taking the dress in is an easy alteration.

Always order the larger size. A professional tailor can beautifully alter a dress down one or even two sizes by pinching the seams and taking in the sides. If you order the smaller size, you run the risk of the zipper breaking or simply not closing at all.

It depends entirely on the dress you plan to buy. If you are buying a gown that allows you to wear a standard or strapless bra, measure with that exact bra on. If the dress has an open back or built-in corset cups and you plan to go braless, take your measurements without a bra.

Roughly 80% of formal dresses require some tailoring to look perfect. Depending on where you live and the complexity of the fabric (beading and lace cost more to alter), a standard hem and taking in the sides will typically cost between $50 and $150. Factor this into your initial shopping budget.

You'll often see this on high-end bridal or custom prom sites. The "hollow" is the small indentation at the base of your neck between your collarbones. The measurement is taken from that spot straight down to exactly where you want the hem of the dress to end (taking your high heels into account!).

While the numerical charts remain consistent, the construction of plus-size and mid-size formalwear is often better engineered. If you wear a size 16 or above, look for dresses featuring a lace-up corset back. A corset back acts as built-in custom sizing, allowing you to tighten the waist or loosen the bust perfectly without needing a tailor.
