Short answer: A makeup bag usually holds color cosmetics and brushes, a toiletry bag holds skincare, hair and hygiene items, and a dopp kit is a men's toiletry bag named after its early-1900s maker. The lines are loose. For packing, the more useful split is wet versus dry, because that decides what comes out at security and what a leak can reach.

A note before you read. We make makeup bags, and we name two of our own products in one section below as examples. The wet-and-dry method works with any bags.
Search for a toiletry bag and half the results are makeup bags. Search for a makeup bag and a fair number are toiletry bags. Somewhere in the middle is the dopp kit, which sounds like a separate category and mostly isn't.
The three names describe who a bag was first sold to more than what it does. If you are trying to decide how many bags to pack, the more useful question is a different one: which of your things are wet, and which are dry?
What each name usually means
| Makeup bag | Toiletry bag | Dopp kit | |
|---|---|---|---|
| Usually holds | Color cosmetics, brushes, small tools | Skincare, hair products, hygiene items | Shaving and grooming items |
| Typical shape | Long and low, or a structured case | Taller, often with a hanging hook or wide base | Rectangular, wide-mouthed zip pouch |
| Lining | Wipe-clean helpful | Water-resistant expected | Water-resistant expected |
| Marketed to | Women | Anyone | Historically men |
Editorial summary of common usage. One brand's own definition is that a toiletry bag holds "skincare, hair products, and hygiene items" and can also work as a makeup bag [1].
BÉIS, which sells all three types, defines a toiletry bag as a travel organizer for "skincare, hair products, and hygiene items," and notes that depending on size and layout, one can also serve as a makeup or cosmetic bag [1]. In other words, even brands that sell the categories separately treat the line between them as soft.
Where "dopp kit" comes from, and where the sources disagree
The term is a shortened brand name. It is generally credited to Charles Doppelt, a leatherworker described as German-born and based in Chicago, whose "Dopps" became a common name for men's toiletry cases [2][3].
The details vary by source. Wikipedia's entry says Doppelt patented the idea in 1919 and won a U.S. Army contract during World War II, and that the company later passed to Samsonite in the early 1970s and to Buxton in 1979 [2]. A leather-goods maker's history says the Army contracts ran through both World Wars I and II [3]. Neither is a primary source, and we could not reach the original patent record, so treat the dates as approximate.
Wikipedia [2] and Portland Leather Goods [3]. Both are secondary sources; dates are approximate.
The split that matters: wet and dry
For packing, the name on the label matters less than what happens at airport security and what happens when something leaks.
At a U.S. checkpoint, liquids, gels and aerosols in your carry-on have to fit the 3.4 oz (100 ml) container rule in one quart-size bag [4]. Solid makeup does not [5]. So a kit sorted into wet and dry has one group that may need to come out at security, and one that never does.
Leaks follow the same line. A cracked powder makes a mess you can shake out. A leaking serum soaks into everything near it. Keeping the wet items together, in a bag with a lining you can wipe, limits the damage to one place.
Foundation, concealer, mascara, serums, moisturizer, cleanser, toner, sunscreen, lip gloss. Subject to the liquid rule in a carry-on [4].
Pressed powder, eyeshadow, blush, lipstick, pencils, brushes, tweezers. No size limit at a U.S. checkpoint [5].
Two if you fly carry-on and your wet group is large. One, with wet items grouped on one side, if you mostly drive or check a bag.
Based on TSA guidance [4][5]. The TSA officer makes the final call on any item.
How we use our own bags for this
Belle Vault lists the Travel Makeup Bag in both its makeup bag and toiletry bag collections, because the layout suits either: two main chambers and four slots, which lets bottles stand on one side and flat makeup sit on the other. For a separate dry kit, the slim Mini Pouch holds brushes, pencils and a lipstick. Those are our products and our suggestion [6]; the wet-and-dry split works with any two bags you already own.
What to do with this
- Sort your kit into wet and dry before choosing bags. That split, not the product name, predicts what comes out at security and what a leak can reach.
- Put the wet group in the bag with the wipe-clean lining. Leaks stay in one place and clean up faster.
- If you fly carry-on, keep the wet group small and easy to lift out. It is the only part the liquid rule applies to [4].

Frequently asked questions
What is the difference between a makeup bag and a toiletry bag?
Mostly the contents they are sold for. A makeup bag is sized for color cosmetics, brushes and small tools; a toiletry bag for skincare, hair products and hygiene items, usually with a water-resistant lining. Many bags work as either, which is why brands often list the same bag in both categories.
What is a dopp kit?
A dopp kit is a zippered toiletry bag, historically marketed to men for shaving and grooming items. The name comes from Charles Doppelt, a Chicago leatherworker whose "Dopps" were supplied to the U.S. Army. Sources give the patent as 1919 and disagree on whether Army contracts began in World War I or II.
Can I use a toiletry bag as a makeup bag?
Yes. The categories overlap, and one brand that sells both describes its toiletry bags as able to serve as makeup bags depending on size and layout. What matters is whether the bag keeps liquids upright and contained, and whether small makeup items stay visible rather than sinking to the bottom.
Do I need separate bags for makeup and toiletries?
Not necessarily. A more useful split is wet versus dry. If you fly carry-on with many liquids, two bags make the liquid group easier to pull out at security. If you drive or check a bag, one bag with wet items grouped on one side usually works.
Does makeup have to go in the TSA liquids bag?
Only liquid makeup, such as foundation, mascara, concealer and lip gloss, each 3.4 oz (100 ml) or less. Solid makeup like pressed powder, lipstick and pencils has no size limit at U.S. checkpoints and can stay in your regular bag. The TSA officer makes the final decision on any item.
Why is it called a dopp kit?
It is a shortened form of the maker's name, Doppelt. His company's cases became so common, partly through U.S. military contracts, that "Dopp kit" became a generic term for a men's toiletry bag, much like other brand names that turned into everyday words.
How we sourced this
Definitions come from common usage and one brand's published definition, labelled as such. The dopp kit history comes from two secondary sources, Wikipedia and a leather-goods maker, which disagree on some details; we could not access the original patent or trademark records, so the dates are approximate. Security rules come from the TSA. Belle Vault makes two of the products mentioned.
