The best girls’ first birthday invitations match your party theme, include enough cards and envelopes, and leave room for the event details. The butterfly set is best for a floral garden party, while the pink mouse design suits a playful pink theme. A pink daisy option offers a simple floral look, and the unicorn set is a flexible choice for a colorful fantasy theme. Check the invitation wording and quantity before ordering; one product below is specifically labeled for a fifth birthday and is not a good fit for a first-birthday event.
| Invitation | Best suited for | Pack details |
|---|---|---|
| Butterfly Floral | Butterfly or garden themes | 30 cards and envelopes |
| Pink Mouse | Pink, cartoon-inspired parties | 20 cards and envelopes |
| Pink Daisy | Simple floral celebrations | 20 cards and envelopes |
| Magical Unicorn | Colorful fantasy themes | 20 cards and envelopes |
| Rainbow Foil Fifth Birthday | Fifth birthdays, not first birthdays | 30 invitations |
Butterfly Floral First Birthday Invitations

This Fablus Store set includes 30 invitations and 30 white self-adhesive envelopes. Each card measures 4 by 6 inches and is made from 300gsm cardstock, which the product description says is easy to write on. Its bright butterfly and floral design is suited to a garden, spring, or butterfly-themed first birthday.
Best for: Hosts who need more than 20 invitations and want a coordinated floral theme. It stands out for combining a larger listed quantity with thick cardstock and envelopes. Consider: The design is specifically butterfly-themed, so it may be less suitable for a party built around a different character or color scheme.
Pink Mouse Birthday Invitations

This set has 20 fill-in cards and 20 matching envelopes in a standard 4-by-6-inch size. The design features a pink polka-dot balloon look, and the cards have blank lines for the date, time, place, and RSVP details. Those printed prompts can make the cards easier to complete when planning a first birthday.
Best for: Families planning a pink, playful celebration who want labeled spaces for key event information. The listing describes these as girls’ first birthday invitations. Consider: The pack contains 20 cards, so compare the quantity with your guest list before choosing it.
Pink Daisy Birthday Invitation Set

Utaqer’s set includes 20 invitations and 20 white envelopes. The cards measure 4 by 6 inches and are made from coated paper. The listing says the paper is easy to write on without worrying about ink bleeding. Its pink daisy design can work for a floral first-birthday celebration, though the product is described as suitable for birthdays across ages rather than exclusively for a first birthday.
Best for: Buyers who want a straightforward floral design and a moderate quantity. Choose this if you prefer daisies to character-based artwork. Consider: The listing does not specify first-birthday wording, so check the card design and plan to fill in any event details yourself.
Colorful Unicorn Birthday Invitations

This set contains 20 colorful unicorn invitations with envelopes. The listing describes them as double-sided, fill-in-style cards. A unicorn theme can suit a fantasy or rainbow-inspired first birthday, but the product title does not specify a first birthday or give card dimensions in the supplied details.
Best for: Hosts who want a colorful unicorn theme and are comfortable confirming the card’s wording and size before ordering. It offers a distinct alternative to floral and pink designs. Consider: Because the listing does not identify these specifically as first-birthday invitations, verify that the design can be used for the child’s milestone celebration.
Rainbow Foil Fifth Birthday Invitations

Not a recommended match for a first birthday. The product title identifies these as fifth-birthday invitations, even though the design is described as pink and rainbow foil. The supplied details do not confirm that the age number can be changed. This option is included only as a comparison reminder: select invitations that clearly match the child’s age, or verify customization before purchase.
Buying Guide: How To Choose First Birthday Invitations
How many invitations do you need?
Count households or recipients rather than assuming every guest needs a separate card. Compare that number with the pack size: the butterfly set lists 30 cards, while the pink mouse, daisy, and unicorn options list 20. Allow a few extras if you expect to add guests or make writing mistakes.
Does the invitation match the party theme?
Choose a design that fits the decorations or overall mood. Butterfly and daisy cards fit floral themes; pink mouse invitations suit a character-inspired pink party; unicorn cards fit a fantasy or rainbow concept. A cohesive design can help guests recognize the theme before the event.
Are the event details easy to fill in?
Check whether the card has labeled blanks for the date, time, location, and RSVP information. The pink mouse listing explicitly mentions these prompts. For other designs, review the card layout and confirm there is enough writing space for the details you need to share.
What size and materials should you check?
Several options are listed as 4 by 6 inches, a common invitation size. Compare the card dimensions and envelope inclusion before buying, especially for the unicorn option, whose supplied details do not state its size. Cardstock or coated paper details can also help you assess whether the card suits handwritten information.
Frequently Asked Questions
What should a first birthday invitation include?
Include the child’s name, first-birthday occasion, date, start and end time if useful, venue, RSVP instructions, and any details guests need to know.
How far ahead should I send first birthday invitations?
Send invitations early enough for guests to plan. Give more notice if people will travel or if the celebration falls during a busy season.
Are fill-in invitations practical for a first birthday?
Yes. Fill-in cards let you write event details by hand. Check that the design provides space for the information guests need.
Should I choose a design that says “first birthday”?
That wording makes the milestone clear. If the card does not specify the age, confirm that the design is appropriate and add the occasion details clearly.
How many invitation cards come in these sets?
The listed quantities vary: the butterfly and fifth-birthday sets have 30 invitations, while the pink mouse, daisy, and unicorn sets have 20. Check the product listing before ordering.
